That's your desired conclusion, not an explanation of how you're reaching it.

And the only way that would make any sense is if you also believe that what Sony is doing wouldn't be anticompetitive even if they were selling their consoles at a profit.

Which makes that argument a complete distraction, given the sheer number of opportunities you've evaded to simply clarify that that criterion (or any other, for that matter) would actually make a difference in your eyes. Honestly, how hard you've avoided approaching this speaks volumes for itself IMO, but perhaps other readers will see this differently.
