Kind of, it's a pretty shit phone, and the creator is not pretending otherwise. Why are you so offended and why should they do whatever you want them to do instead?
Why does the end product of an electronics learning project need to be useful? Or any hobby project? Your criticism was that their hobbies should yield something useful, but where's the "justification" for that? What's wrong with just having fun?
I think most linux users do, depending on what you mean by caring: more adoption would be better for software support and consumers in general.
But what think is actually weird is to hope for the opposite and to care about that people cannot play a game on linux. Nobody will be forced to play EA games.
I don't and wouldn't really play the kind of games that use it, but nice. Though also I don't know what running this on proton means. Kernel level is not nice.
Solution to what? Electronics hobby? Dictating what people's projects should and shouldn't be is kind of an asshole thing to do.
