@lps Thanks!
It's partly out of necessity. YouTube doesn't allow me to post my "teaser trailer" videos for my classes, which often have copyrighted music (which I acknowledge) but used for parody purposes.
YouTube has also flagged some teaching videos because they are about using scientific thinking to test claims, but their algorithms think I am advocating for those (sometimes dangerous) claims. It takes work to undo their block, and I grew tired of it.
