To the downvoters: YouTube has been, for a couple years now, conducting a natural experiment that my confirms my claim. People can either buy a subscribtion or suffer the ads. Most prefer the ads.
I don't think that's a good experiment, though. Regardless of people's overall preference on this, I would expect the existing YouTube audience to mostly stay with the ad-supported stuff, because that's what they're used to with YouTube and people who really, really hate ads weren't using YouTube to begin with. All of that makes YouTube users a biased sample.
A more valid experiment would require all users to be new to the platform.
