Most people talk about Religions people being fanaticists with a disregard for human wellbeing. (Outside of their religion) I associate this with the sects that emigrated to America due to prosecution in Europe and American New religons. (Amish, those Utah people etc., those wierd evangelicals(?))
Of course there are also good religious groups in America.
By this metric youtube is not enshittification to some extent. They are a household name and not some weenie startup.
It being ineffective is a necessary part of it, in my opinion.
