I totally get that they had to find some way to financially support the massive infrastructure that was necessary to do what YouTube does.

I was fine with an ad every now and then.

I was fine with an ad at the start and end of a long video.

Ads on a 30s video? Ads on an Ad? Multiple ads at the start, multiple ads in-between and at the end? Jesus h. Christ. Removing the dislike button?

That was when I switched to ReVanced.
