I thought they stopped making the source available because it made it
too easy for the counterfeit products. At least that's what I was told
about the SDK (which contained the source).
Call me crazy, but they could release whatever modifications they made
to GPL code and still create closed source binaries that run in
userspace to do whatever trade secret stuff they need to do. Isn't that
how Mikrotik does it?
