You can only sell for those devices with manufacturer licensing (that includes profit sharing and mandatory annoyances like “achievements”), and consumers can only buy games licensed by those manufacturers.
The only difference is that PC developers haven’t experienced that before. It seems like this would have been established in the 80s/90s, so I’m surprised we’re getting to court - is there a change in judicial philosophy?
That said, as far as I can tell every platform charged the same ~30% so I’m sure any company can simply point to the entire market as having established that under fair conditions (after all, if there was a cheaper platform surely they’d prioritize that?)
