Re: [Trisquel-users] free software to remove DRM from Adobe ACSM format

[onpon4]

Any program designed to break DRM is illegal, so as a general rule, breaking  
DRM is not easy. The one exception I can think of is CSS (used for encrypting  
DVDs), but that's just because the encryption is so weak that it can be  
brute-forced very easily (so despite the illegality of it, all kinds of  
programs designed to break CSS exist; libdvdcss is just the most commonly  
used).
