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.
They should really be selling Big Buck Bunny DVDs in all their examples, they're going to get fucked sideways if they suggest anything remotely questionable in any official context.
