No it's not.

I mean, maybe it's trying, I don't know, but I'm not even trying to keep ublock origin up to date (maybe it updates itself in the background?) and I haven't noticed any difference (or ads) other than the normal progressive enshittification of both platform and channels, and I'm pretty certain I live in the world... EDIT: And before anyone asks, I am logged in, I mostly use YouTube through the subscriptions page, so being logged in doesn't seem to be causing any problems for me either.
