It's like comparing car (PC) vs bicycle (Steam Deck) vs train locomotive (Xbox/PS).
Car can get you almost anywhere in the world, bycicle mostly in the same city, but you can go hard and get into another country. And train locomotive? From point A to B. That's it.
Ya but that situation doesn't really fit into this comparison of another issue very well. The closest thing I could think of would be comparing it to, say, oil companies doing something like that to give one of the others summer kind of disadvantage
The point is that differences between PC and Console are exclusively artificially built on the console side. A mere Raspberry PI 5 can fit in the PC sphere (minus hardware modularity as GPU (...even if eGPU...)) in every aspect: anything USB, including printing or complicated CAD hardware are fully compliant with Linux.
The hardware in the console are even X86 (PS4 can run Linux with some tweaks).... but you can't run a working browser on the PS5: this limitation is artificially built by Sony because otherwise you could play free web videogames. There's nothing technical in these limitations, the console are just PC hardware capped to the platformed holder (Sony or Microsoft), and the difference is just made by axed functionality and billions spent in advertising propaganda.
