Actually you haven't. This has been a very reasonable discussion.

Here's the difference: AVR software is tightly coupled to the underlying
hardware used in embedded systems. The type of software that is typically GPLed
and used by millions is for general-purpose computers: PCs running Linux, with
all the various GNU software. Embedded systems are typically proprietary, and
they're certainly not very general purpose. These proprietary systems are
typically built by commercial entities which has interest in certain part of
the software, whether for intellectual property (IP) or trade secrets, or at
the least for competitive advantages. They won't use GPL software. The
potential user base for GPL crypto code for the AVR is tiny, at best. It will
very likely stay a curiosity. It certainly will not foster "community
development". The community will consist of students and hobbyists.
But as it has been pointed out, there are alternatives such as LibTomCrypt,
though AFAIK it has yet to be ported or vetted for the AVR.
