Re: [Trisquel-users] which law(s) prohibit people from circumventing proprietary formats?

[onpon4]

It's only things like DVDs that are forbidden this way. Patented formats like  
MP3 and MP4 are patented; developing or using software that implements the  
idea violates the patent and can get you sued. Both patents and laws against  
circumvention of digital restriction mechanisms effectively censor free  
software, but they're otherwise different.
