I'm getting a lot of Ouya vibes from this project. Good UI/UX is hard, and "open platform" might get some kickstarter monies, but it isn't really something 99.9% of people care about.
At the very least, they won't be trying to chase the fickle gamer market. It seems like Librem 5 is trying to cater to hackers, who would be the most tolerant of deficiencies in the UX.
