I think you somehow missed the main point of my comment.

Not to diminish other companies for bringing hardware to market, but Valve is also funding the developers of the open-source software that makes games built for Windows run well without Windows, and is providing free support for it, with great success. It has dramatically improved the Linux gaming experience not only for handhelds, but also for desktop gamers. Including people who don't use Steam at all.

(And sadly, Lenovo, Aya, and GPD answer to and help to fund an incredibly predatory government that I do not want in my life and cannot in good conscience support.)
