At some point the ratio of convenience to quality got all out of whack. Most people I know use maybe three different platforms at most and get angered by all of them. My internet experience peaked when I was checking 20 extremely specific forums regularly and using in-game chat 90% of the time (vent/teamspeak were reserved for raid night).
If a company has no competition, being a monopoly, it's basically free to do whatever it wants. Youtube controls the video streaming market of the internet. If they choose to not pay content creators, to run 10 ads in a row every 3 minutes, or to ban content creators for saying something their automods think is a bad word, what will you do? Where else will you turn? Odds are there's nothing for you on Vimeo. So you either make do with how Youtube operates, or you don't get to watch cat videos, or video essays on WW2, or playthroughs of Super Mario Sunshine, or what have you.
