> the current state of ARM Linux is depressing. Every vendor bolts on their own custom mess: closed boot blobs, vendor-specific patches, "board support packages" that nobody outside the chip maker can really understand

Fixing this is a noble goal but won't sell a lot of devices by itself. And it will only fix the one specific hardware configuration used by Flipper. This seems to be the only interesting part of the project and the actual hardware is otherwise completely uninteresting. Not sure how they expect to succeed here.
