"You pay and it's yours." Which is exactly why, having paid for an ad-free service, people are miffed when ads appear anyway. I'm not going to take on the responsibility of educating you as to the examples that exist, because that's your own responsibility. Not only because we have to educate ourselves, but because you made the unsupported claim in the first place that the phenomenon doesn't exist. Proving a negative is very difficult, as we with all this glorious mental firepower know. In a world this large, it's a poor bet on a statistical basis alone.

And youtube could easily ban third party sponsors in their ToS, have all advertising on their platform go through them, and completely remove it for paying customers. Just like Netflix can refuse to host any shows with product placement. It's entirely their own product decision to allow ads in their "ad free" offering.
