That doesn't make them bad, just not as secure as advertised.
It's bad that they're fragmenting Linux community once again for this kind of project (other projects are fine when fragmented, but not this one).
And security in this very project IS essential. Running random untrusted binaries on your system outside of a functional sandbox is plain stupid. We don't need another Windows system.
Besides, isn't Pyra planned to run Wayland anyway?
I don't know. OpenPandora was the best gaming device I ever had, so I just expect to use Pyra to run games on whatever system you guys think it works best for you. Wayland has that "every frame is perfect" and "better battery usage" propaganda, but I don't know how well it plays with closed source hardware drivers. The xwayland layer for old software may be suboptimal, but at least SDL2 already seems to support Wayland, so we're half-way there.
