A lot of platforms have arbitrary requirements of who they'll serve or won't serve. Even those with fixed rules can enforce against anyone, and then just ignore your support tickets when you try to appeal.

I guess the difference in this case is targeting someone due to a disability/protected characteristic, compared to some other reason. One fair thing might be Uber subsidising rides of disabled people with guide dogs (in the sense that it pays drivers a bit more to account for cleanup costs etc). I dunno if they can be expected to do this, but such costs probably won't show up on their bottom line and the PR of doing that alone would probably make up for any costs.
