Nevertheless I think Apple are making some missteps. I think they made a mistake on the game streaming service decision. Epic can go take a running jump though.
I think you're getting a bit hung up on the language -- "appliance" and "console" are trying to communicate basically the same thing, e.g., a device which on a technical level could absolutely be a general purpose computing platform but has been restricted from that by design.
And even assuming the antitrust/monopoly argument holds, is there some barely-known exception to “general devices only”?
I’d love it if I could load my own stuff onto consoles, but don’t see how this could be practically compelled in a way that isn’t massively impactful to _everything_, especially with security and piracy implications.
