Did nobody watch the linked video? It's obvious he had comments restricted because his comment was deemed as abusive, and not because it was critical of "hiding dislikes".
"That's not abusive at all", you may be thinking. But calling others names, even something as nonsensical as calling them a "handjob", can still easily fall under their terms of use.
If you refer to the original video[1], people are nothing but critical of the change. Why aren't those being disappeared? Maybe because Youtube doesn't care what people post as long as they follow their terms of service.
