it's because Youtube is a content monopoly. TikTok is a platform for short content...on youtube it's a feature with shorts. Twitch is a platform for live streaming content...on youtube it's a feature with, other than discoverability, the same features. Any music streaming service? again...it's a feature on youtube. The fact I could export my playlists from any music streaming platform and import it to Youtube and listen to it ad free via an ad blocker? come on. So as opposed to using multiple platforms, with youtube you have it all in one place. So no, this will not get people to stop using it.

Premium you don't need if you're even the slightest bit tech savvy. but no one is ever going to stop using youtube, there's no point. I mean I use peertube as much as possible but every now and then I'm back on youtube because of all those features in one place and some things I just can't find on peertube.
