I do not agree with their changes & policies but I think you underestimate the market share Youtube has in this area. Also you are not the average Youtube user (being on Lemmy and all) so you should think about how the average user interacts with the platform (they don’t care about Ad’s & don’t know how to install an Ad Blocker). I think Youtube can do a lot more shit before normal people would start to jump ship, but even then what are the alternatives for them? Peertube etc. don’t have the content they watch…
