At first I thought so too, but I believe those might still work as long as the attestation feature doesn’t end up in browsers. Those applications likely can still pretend to be web user.

ReVanced is special because it patches original YouTube. So if the original YouTube would start doing this kind of verification, after being patched it would stop working. To fix it the whole playback code would have to be replaced, but at that point why not use NewPipe or GrayJay.

BTW: Google is doing that because it has monopoly in that market. They similarly have monoly with browser market. Still after uproar they backed off. We really should try to break it and apps that support multiple platforms (like mentioned NewPipe and GrayJay are probably the best way to dethrone them)

Consumers have created this future by flocking to YouTube and nothing else.
