Because it was mostly people whining who don't own the adapter but were complaining it won't work with their screw drive lenses on the camera they own. I want reviews tested on non screw drive lenses on cameras that Sony says it will work on. The few people who tested it properly gave it high marks.

Here's an example, 1 star.

"The main feature is the motor. But it doesn't work with most cameras (A7M3, o A7-C for that matter). It's ridiculous, for most people this adapter is useless."

Well I suspect that "most people" don't own any screw drive lens (me for example). I am interested in how well it works with newer A mount lenses with a built in motor both Sony and 3rd party. If my A99ii ever dies I need to know how my lenses will work on a camera like the A7rIV.

I own plenty of screw drive lenses. 135/1.8 ZA Sonnar, Minolta 200/2.8, Minolta 85/1.4 among them. Plenty of people own screw drive lenses that they may be interested to adapt in the future. I doubt "most people" only bought the more expensive motor drive ones. In any case, why make an adapter that only works with screw drive lenses on the 3 most expensive bodies?

When I say "most people" I'm including all the lenses that were sold after Sony bought out Minolta. For that reason I suspect SSM and SAM lenses easily outnumber screw drive lenses.

I don't know how any of us could determine the ratio of existing screw-drive lenses to existing motorized ones. Screw-drive lenses were made for about 17 years before the first SSM lens even appeared. After that, motorized lenses gained a lot of traction, but old and new screw-drive lenses remained in the lineup and remain there even now.

I also don't know how any of us could determine the present ratio of users who own only motorized lenses, which would be a completely different thing.

Let's just say that plenty of people continue to own and use screw-drive lenses without trying to guess at a ratio.
