No. By the four software freedoms, one must be able to modify the code 
of any piece of free software. This requires the code in its original, 
unobfuscated non-binary form. When RMS says that software may be private 
and free, he likely means that it can be developed by a private business 
for industry. But, again, for it to be free it must retain the four 
essential freedoms.
