I think you're wrong. I'm a big advocate of open computing, but I think that endpoint autonomy is in as much danger as it ever was, if not more. You're describing that legal challenges to market-based or grassroots ad skipping etc. have failed, but consider that the legal route is out of fashion. What companies do now is sell a locked device. See windows on ARM, safetynet, [whatever apple is doing]. I love this click-to-root hack, but it's really a "play 2009 games, win 2009 prizes" situation. Good luck trying this on a game console or an Amazon echo.
