Every time I see a creator I like do a "smooth transition" from content to ad, it makes me feel betrayed. Not only are they about to read words someone else wrote for them and which they don't really believe, they spent an extra 15 seconds pretending it was part of the video in order to keep my full attention when they throw the sponsor name in my face. It's scummy behaviour.
Creators need sponsors to pay the bills, just as they do ads, I get it. I don't fault them for the industry basically forcing them into these kinds of "integrated ad reads", as well as the fact basically all the sponsors have huge ethical problems. But I will not subject myself or the people who watch videos with me or on my devices to this brain rot.
That's why I try to support them in other ways (YouTube Premium, Patreon, etc.) and run adblock and sponsorblock on everything. By my napkin math, they make more this way anyways.
