Does this mean the 1981 IBM PC gets the same praise? I mean you could install whatever you wanted on that thing.

Tell every game console maker.

For the sake of the argument, the topic here is running software on general computing devices, and most people don't put game consoles in that category. Also, according to my poor knowledge of game console history of past 30 years, game consoles never intend to run arbitrary software, unless you jailbreak the device which is obviously not allowed by ToS.

You are allowed and maybe have one option, what's the problem?
