how much actually ends up in the creators’ pockets
For most, very little. For the big ones, millions of dollars, and I always resent people lecturing me about “morals” because I’m not willing to subsidize a rich person’s hobby.
Regular perople aren’t making anything from YouTube, only the ones who had the capital to invest in their channels upfront. I don’t feel compelled to pay for any of that, and I’d just as soon have their content filtered from my feed if it’s immoral not to want to see ads.
The channel I use most often is Audible Anarchist, and I really don’t think they give a fuck if I use an adblocker or even Piped to watch their videos.
