I don't know why you're getting downvoted. I'm not sure I agree with you about ownership, but it's a point worth considering, as are your other points.

Also, I like the idea that it's not services themselves that are the problem, but rather platforms being used to force them down people's throats. Coming up with policy to discourage services seems much more conceptually difficult than rediscovering serious antitrust, a simple oldie-but-goodie.
