Pretty good analogy though. Steam has some ads (out of the box it literally launches an ad window at startup) but it isn’t really a pain in the ass about it. You close the window, you move on, it only happens once and there’s nothing unskippable. It doesn’t shove ads in front of my face every time I launch a game from the library (I’d immediately leave the platform if there were.)
Fact is if steam and the other major platforms were ever to devolve within striking distance of how bad youtube has become, piracy would become unhinged. So far Valve has resisted the illusory “infinite money lever” that idiots in c-suites have misunderstood ads to be.
