I wouldn't say so. Valve's business is selling PC games.

Wine is not an emulator, and has nothing to do with projects as Yuzu, Dolphin, PCSX2 and others.

through given how mainstream the switch hardware is you could argue that Yuzu isn't that different to WINE as you don't need to emulate anything but just provide compatible OS interfaces like WINE.

(if running out on ARM, there is still ARM to x86 emulation but that is just generic ARM to x86 emulation which has not that much to do with Yuzo per se)
