I imagine Epic wouldn't be opposed to getting their own App Store onto a Nintendo Switch where they can keep 100% of IAP revenue from games like Fortnite, as well as host other developers' apps and charge them a commission. All while free-riding on other companies' hardware. But PR-wise, it's probably easier to target Apple than go after Nintendo, since there seems to be this implicit understanding that a game's 30% cut is there to offset the game console being sold at a loss, and so nobody really questions it.
Also, what exactly is the difference between a console and a computer? For instance, the steam deck is primarily aimed at running games, but it can also be hooked to an external monitor and used for productivity.
In theory, there's also nothing stopping Microsoft from releasing Office for the Xbox and PS5 as well, since those support keyboard and mice. Software is software at the end of the day.
