Is this youtube staff purposefully deleting critical comments?

Or is it anti-spam algorithms getting triggered by people flooding the comments sections of videos with the same inane comments? And/or getting flagged by creators and other youtube users?

Frankly, I can't see most creators wanting their youtube video comments full of "BRING BACK THE DISLIKE BUTTON", and I could see lots of their fans being annoyed by such comments as well.

My guess is that 95%+ of youtube users are more annoyed by an extremely vocal minority disrupting things than they are the removal of the dislike button.
