That's sounds plausible.

By releasing the driver?  I don't think so.  They don't think we are
such idiots to take their code and get in trouble, do they?

Besides, Broadcom contributes to the kernel.  There are files with their
copyright, even in the SSB code.  They just don't want to help with the
wireless driver.

Reverse engineering efforts should always be careful about the legal
aspects.  Yet I see two possible loopholes.

1) The recipient is not necessarily bound by the license without having
signed it (in some jurisdictions).

2) Reverse engineering to the purpose of compatibility may not be
restricted (in some other jurisdictions).

Even if neither applies, it's not like we are losing anything.  We
should just be careful, as always.
