I'm paying for YouTube Premium and I fully expect them to do the same thing once they've squeezed the lemon dry and need to find more money in this perverse game of rentier capitalism.
I've gotten really good at tapping the skip-forward-10-seconds button a couple of times whenever the ad comes up.
The only creator where I don't do that is Acerola, because he puts a video of him playing with his cat in a pip view during his ad. I can zone out for the ad and enjoy the cat video instead. Win-win
I'm so glad people have made sponsorblock
Step 1: Create an ad free "premium" experience for a price
Step 2: Raise prices
Step 3: Create a cheaper tier which is "ad supported"
