If you were watching YouTube videos without watching ads, they were losing money on you. You not watching videos on YouTube is going to be a net gain for them.
Many instances are having growing pains, and figuring out which apps aren’t crap is difficult. On iOS, I’ve been pretty happy with Memmy, though Lemmios is good too.
