That answer is wrong. As said before, cropping IS the same as using another focal length when you consider perspective (it affects other things I listed: resolution, DoF, DR and noise to signal ratio)

Yes quite right. As Jeff pointed out on my initial reply, perspective does NOT change when just cropping. I admit my wording was off when what I meant was perspective changes when framing (and re-framing) at different focal lengths.

I DID do some testing so hopefully this clears things up:

Below is a shot taken @23mm with the 1.4 digital teleconverter on (so approx 35mm equiv):

and one taken at 35mm:

To further demonstrate below are two shots, one taken @16mm (with 2x crop) and one taken @35mm - both images have same perspective but different DOF, noise etc:

Conversely, the point I was making initially (and what others I believe are making) is the change in perspective when re-framing a shot. Below is a shot taken @23mm then re-taken @35mm but reframed so the subject (lens hood) is approx the same size:

Allright, You just saved me a lot of time and effort to perform similar test - thank You!
Seems like all clear to me, beside effect of  background "compression".
Maybe its just lack of my imagination, but Its hard for me to belive, that images taken from XF 90 and Laowa 9/2.9 (cropped to match XF 90 perspective) will have same background compression.
