Cohen and Navin made a deal with the MPAA to remove links to illegal content on the official BitTorrent website which opened the door for 3rd party tracker sites like the piratebay to do so.

I imagine this will happen with OB the official app will be crippled by lawsuits but of course this all depends what they have told each other in private unencrypted emails and the dev mailing list. There's already a thread where Patterson advocates to recommend suggesting that developers talking about OpenBazaar with the public cite example products that are “illicit but socially acceptable" such as Fireworks and Radar Detectors. “Stuff that people wouldn’t disagree with but is technically illegal to sell because of stupid laws.” Seems nobody has learned from the Megaupload case how you can talk yourself into problems with overzealous prosecutors.
