I think your theory is plausible. On the YT smart TV app, the ads seem to be increasingly about unpleasant things like dick pills, period pads, and constipation treatments. I think they literally serve up unsavory ad content as a way of punishing you into shelling out for a subscription. Jokes on them, I just switched to SmartTube.

The annoying part is how many mainstream tech companies have ham-fisted AI into every crevice of every product. It isn’t necessary and I’m not convinced it results in a “better search result” for 90% of the crap people throw into Google. Basic indexed searches are fine for most use cases.
