[Trisquel-users] Re : free PDA running JMP

Some are violations of the GPL, e.g., binary disguised as source code.  But  
proprietary firmware (the largest problem, nowadays) arguably is not.  It is  
and executable file that the kernel only sends to the peripheral that runs  
it.  So, it indeed looks hard to argue that Linux + the firmware blobs is  
derived from Linux alone.
