Has Viltrox AF 85/1.8 RF been removed from Viltrox homepage?

That looks like something produced by a patent lawyer who normally writes lens patents. The specified claims appear arbitrary, and IMO lack any inventive novelty. Much of the claims repeat earlier claims, and the whole thing reads like someone trying to patent a gearbox with a certain gear ratio.
That patent was filed on the 30th May 2018, several months before the eos R was announced. That's sufficient advance notice, it's just that the patent process is very very very slow.

Yes, that's fine. You are also correct in characterizing most of this patent as BS. However, the notion that there is some patent applying to the idea of an electronic contact on a lens fitting into the RF mount isn't based on any actual patent Canon has or for which it has applied, nor could a patent be granted for that simple idea.
Ah, apologies - I misread your post

It makes sense to Canon. Mirrorless is different than DSLR, in that there will be no AF issue even with third party lenses. With an EF mount Sigma lens, we have to tune for different distances and different focal lengths. This tuning thing is not perfect, you may have to tune it again on another body. It's time consuming either. But when put them on R5, no tuning needed, everything works perfectly. You just can't tell the difference between first party and third party. So the RF third party lenses will apply more threats to Canon than they're on EF mount.
In my impression, Sony is more focus on sensors and camera bodies, Canon more on their lenses. This may explain their different tollerence to third party lenses.

Oofah, Canon. Maybe you should take a page from Panasonic's book...
Panasonic LUMIX S Series Camera Tutorial : Lens Adapting - YouTube
...and encourage adapted-lens creativity on your platform. Panasonic clearly has some serious bragging rights here, just one of the reasons I ditched y'all, Canon.

This was Canon’s mistake. Sony started opening their E mount up… with limitations for third parties. Their own lenses have advantages in burst speed and top AF performance, but those unable or unwilling to pay as much money can settle for third-party alternatives.
Third party lenses have been taking sales away from camera manufacturers since time immemorial. Nothing has changed, really, except that greed has finally consumed the last ounce of common sense from Canon’s board and top executives.
Sorry, but that’s a wrong impression. Sony Semiconductor is a wholly independent corporation from Sony Electronics - they don’t share profits, inventory, or anything else with the division that makes cameras. This was done to protect the part that makes sensors from the flak that the Electronics corporation was garnering.
Canon, on the other hand, keep a high level of integration between their semiconductor and imaging operations.
Canon want to become the Apple of the camera world, walled garden and all. But they don’t have the vision, innovation or marketing of Apple. I don’t think this will end well for them.

Last nail in the coffin for canon imo, loved the eos-m, most ef glass, canon colors, and the rp & r5, but, there is a dearth of practical glass on rf mount, and this is going to make it that much worse.

You have said that the lens reports itself to the body as an EF lens. It is therefor not an RF lens. It does have an RF mount that also prevents it being an real EF lens in that it can't be used on an EF mount body.
I have looked at the B&H page for the lens. I have not seen anything that says that this is an EF lens protocol lens with an RF mount.
I believe that in the UK and EU, the description of the lens must be accurate. RF is not correct as the lens itself states that it is an EF lens. I also can't be described as an EF lens as it does not have an EF mount. If the description is incorrect, imports can be banned and stocks siezed and destroyed.
It is not in the interest of Canon or the end user to have a range of RF lenses where some are real RF and others are EF in disguise and dont support any RF features.
I suspect that there would be a lot of complaints is someone produced some Sony APS-C lenses and marketed them as Full Frame because they can be mounted on a sony FF body and work (in APS-C mode).

OK, but such a lens could easily be described as physically fitting on an RF mount and supporting autofocus using the EF protocol. That's not a real problem in a serious way. (I also don't know that it didn't report being an RF lens somehow internally, that was only what could be assumed from its EXIF identification.)
I agree. Seems like something Canon would do eventually.
Not sure what the "RF features" you mention are, but a lot of Canon's new lenses are pretty much EF lenses with an RF mount or, in the case of the very long telephoto primes, they just stick an RF adapter on the end of an EF lens. Gee, thanks Canon!

I can't see how dropping a basic feature that increases the attractiveness of Canon's bodies would sell more lenses. It would be akin to cutting off your nose to spite your face.

Could be, although I think the goal is to rob peter to pay Paul.

The idea that Canon would prevent you from using EF lenses on RF cameras is absurd. They have never artificially limited how you could use older EF lenses... You can still use the very first EF lenses dating back to the 80s if you want. They still exist and still work the same. There is no basis for saying this, so why make things up? I am certain that support for EF lenses will remain the same.
Sometime year the line, Canon will probably eventually stop manufacturing the first-party EF lens adapters. That day is far away. They still have EF lenses that aren't replaced by RF lenses. And they know that people buy used lenses and use them.
The RF lenses are often optically considerably better than their EF predecessors (e.g., the fast 50 and 85). There are significant improvements. But if you want to use an EF lens, that is supported and will remain supported. Canon has never dropped EF support, and a significant part of the RF system's design is that it seamlessly supports using EF lenses. (In fact, no mirrorless system supports AF DSLR lenses better than RF supports EF.)

I'm a Canon shooter sitting on the sidelines right now watching RF unfold. I've got a full kit in EF bodies, lenses and flashes that I've built up in over a decade in the system. I'm happy with it for now and no immediate plans to upgrade. I'm basically in a holding pattern for now and just using what I have.
But...at some point I know this gear will need to be replaced. Watching the direction the market is going I will admit Sony E mount is looking much more attractive to me than it did just a short time ago. Most of the lenses I want only exist in that mount. Sigma primes and Tamron zooms have got my attention.
RF so far has been filling the top and the bottom of the system, and leaving the goldilocks mid range sorely neglected IMO. Their L primes are either too pricey, too big, or both in my case. The non-L offerings just don't excite me. The RF 70-200/4 I really like, but it's the only lens that I really want. That's not enough.
Canon has a few years to figure it out before I'm looking at some major upgrades. Maybe by then the lens situation will be fleshed out, and if we have some of these excellent Sigma and Tamron options available. But if not, I have no brand loyalty here and will vote with my wallet.
