How are you this stupid? I already said in my own post that Rifftrax has to purchase licenses or use public domain when they sell movies with their riffs. Learn how to read before you reply. Linkara doesn't own the rights to jack shit, and most of the comics he reviews aren't in the public domain.
Did you actually read the case you're citing? 2 Live Crew did a parody of a Roy Orbison song. A parody. Do you even know what a parody is? They recorded their own version, with their own instruments and vocals. They didn't play Orbison's version and tell jokes during it. What Linkara does is not parody, it's riffing. A commentary track with jokes over an original work is not a parody. Learn the difference. If Linkara wanted what he does to be parody, he would have to redraw the panels and rewrite the dialogue himself.
Gotta be honest, that'd be fucking hilarious
