The calculator firmware is a "software application" that's run by a user on a mobile device but it can't access an application store or download applications. For that you need a PC.

So github.com is the violator, here, since it's a software application that may be run by a user on a computer and can download applications (loads of them!).

I've read through the CA law a couple of times and can't figure out what an application store is supposed to do. What part of the law would github violate?
