What made me and I imagine a large chunk of other people convert to revanced/similar apps is the super aggressive advertising, it’s impossible to use youtube when you get a double ad before and after every 5 second video and get 30 second midrolls every like 3 minutes. You can’t skip through a video to find the part you want to see because you’ll just get an ad. It’s extremely infuriating and time-consuming, it used to be where I was willing to deal with it but they fucked it up. Now I can never go back to ad-riddled YouTube, even if it has a “reasonable” amount of advertising (I am now in the belief that no amount of advertising is reasonable anymore though).
