Sure, but that can be said about almost anything.

Still, I’d be surprised if they went the route of embedding ads into the stream, in part because of measurability/skipability/etc. It’s definitely not out of the question, but I think we’re still ways to go before we get there.

And even then, tools like yt-dlp would probably be able to apply some heuristics to figure out which segments are foreign to the stream and slice them out that way. Blocking yt-dlp would require DRM, which in turn requires changing the transcoding pipeline in a pretty non-trivial way. I also doubt they would willingly go this route.
