Google has slowly been really pushing their way or no-way. They announced that 3 strike policy against your account for ad-blocking, from my understanding it had only rolled out to chrome but someone within the last couple months posted an image of Firefox showing them the adblock message.
Ublock Origin does still work for some, but I believe it’s per account. Honestly, the moment I heard about the policy I immediately switched to Piped. I don’t really care about the YouTube algorithm, I hardly use the site outside of information searching (guides mostly) and so the homepage always being YT front page doesn’t bother me. I can create an account with piped and have subscriptions, can make playlists and on the LibreTube app I can download videos. That’s all I need. Unfortunately there is some downtime sometime but you can host your own instance of it really gets to you - I’m nearly at that point myself just for the peace of mind.
So, fuck YouTube and Google tracking, fuck their forced ad policy, use a wrapper like Piped/Invidious and be done with them.
