I mean, GPL guarantees code remains open and free. If they release an app based on the source code licensed under GPL, they have to give a source code along with essential build instructions to anyone who is using it, and then you can do anything with that code, including sharing, compiling, and distributing that app, provided it’s under GPL license.
Edit: I see it’s licensed under GPL 3.0, so no worries.
I think ARM is their end goal, it’s really the only option for a handheld console, as today ARM is the only way you’ll get enough performance/power rate to make it both good on battery with good enough performance.
Win-win for everyone if they invest in an open source x86 to ARM project, similar like they did with Wine.
The correct way of implementing chromatic aberration would be like the one on the “corrected” side. There is still some, but it really is subtle.
Anyway, I don’t think games are a good target for chromatic aberration. It’s really meant for photorealistic scenes, mainly photorealistic renders, that give a sort of uncanny valley effect without it.
But once again - it looks stupid if your scene is not photo-realistic in the first place.
They are great:

(Unless you want to complete additional levels, which are still canon, then much much more).
