I can't run my Switch copy of Warframe on my PS4. I have to install Warframe for PS4 on the PS4, and then I'll be playing only with other Warframe-on-PS4 players.

Similarly for every paid title I have on the PS4 if I move to Switch I have to buy those titles again, assuming they're available on the Switch. Many of the titles I have on Switch require a Nintendo Online account which is a paid service.

So I'm not sure what you think you're addressing with that comparison, other than desperately trying to find evidence to support your assertion that iPhone is somehow different to a gaming console in terms of being a platform or device.
