Antitrust law exists exactly to prevent companies from making their own ecosystem/walled garden that competitors cannot sell into. Product tying (forcing you to buy product B in order to buy product A) falls under that umbrella. Game console are not magical in this regard.
Lots of us have a problem with all of those things, and would like the government to enforce the law. I've never bought an Apple product, and the last game console I owned was a PS2 when I was a child.
I don't see how that's related (e.g. Android is FOSS but can use attestation for monopolization), but I do think we ought to make the law require products that contain software come with source as a consumer protection measure.
