We recently upgraded to YouTube premium to get away from the pestilential commercials and I find myself taking in more and more content. In some cases it can be educational, for example I've been watching various channels about how car dealerships work and what to know and/or avoid. But I realize it's just well packaged opinion and I still have to make my own decisions about it.
YT channels are, to me anyway, more like Wikipedia and you can't cite Wiki as a reference in a formal paper. It's useful as far as it goes but there's an awful lot of credulous people out there and a distinct lack of critical thinking.
