Seen that from time time. YT messes with whatever ad blocker you're using, the ad blocker updates, rinse repeat.
Why YT refuses to offer something like a $5 a/month ad free subscription is beyond me. Instead they only offer their $14 prime service which includes things 90% of people don't want.
Though I have to say, as much as I am a google hater, the other streaming services have gotten so bad and so expensive that I have considered doing just youtube (not youtubetv). I seem to find myself watching more youtube than anything else these days, and they're pretty much a "standard" streaming service these days as well. Over Christmas, I bought all of the "The Office" Christmas episodes to watch, and I'm pretty sure doing that was cheaper than a month of Peacock.
If the standard youtube subscription was the $8 student rate instead of the $14, I probably would be subscribed now, especially with the included youtube music, which seems to be better than the shitshow that Amazon Prime Music has become. When you think about what the other services offer vs what youtube offers, the $14 isn't really all that out of line, IMO.
I think people (including me) complain about it because youtube started free*.
*Free, other than the mining of your data, of course.
