Hi, HN! Author, here. Yeah, I was a little disappointed by the GPL and attribution issues, too. But also, I feel a little bad not having given them too much time to respond, or too much heads up that I was gonna write a piece about it. So if anyone has a way to reach out to them, I don't want to trash them too much, and I'd be really happy to update that blog post!

But also, the other side of this is that the attribution issue is, perhaps, only 50% of my thrust here -- the other 50% being that it's actually a really cool device inside, and it's neat to see how they managed to build a device that's (mostly) competitive with Garmin's rich feature set so quickly. And so that, I think, might be what would be even more interesting to HN, rather than just torching them. If they opened the platform up to tinkerers a little bit -- perhaps if they 1) unlocked the bootloader; 2) provided /system images; and 3) enabled a switch to give you access to adb -- then it would be a really really cool form factor of a toy for a lot of different uses.
