Isn’t official support legally binding, or seen as that by a regular consumer, or their board? Like, they just don’t provide anything to other OS unless they can troubleshoot here. And they are donation-based too, meaning they are very alarmed about any liability, or any unpredictable sutuation at all, since both cash and questionable consent are involved.
I don’t thing Deck can take a dent here, but there are a lot of cheap chromebooks and the likes in edu, where their primary targets are. I think they can bank on it. But it’s good they weren’t as smart to do so.
