Rawdogging YouTube today is a similar experience to what I had with a free trial of Hulu several years ago. The ads were so frequent and so lengthy that I cancelled several days before the trial was even over. I swear I was getting six minutes of ads for every two minutes of content.
There's a point where the greed makes the product unusable.
I watch a lot of Tubi on my TV, and I find the ads there tolerable. They don't just flood you with them. I'm totally ok with sitting through their ad breaks in exchange for a free watching experience.
(I don't know if Hulu has gotten better or worse. The experience was so god awful that I've never even slightly entertained the thought of trying it again)
Twitch is the same. I don't block ads on Twitch because it's usually just a minute per half an hour to 45min of video. It's even better if the streamer initiates the ad breaks manually, like when they stand up to stretch/walk around, because then I don't even miss anything. That's reasonable and fair, although they do have pre-roll ads and those obviously suck.
