What is your point here? Yes, if I were to pay for a movie or show, I would find it unacceptable if it were to contain paid product placement. Do you think prominent logos in media are an accident?

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.
