Well well, isn't this quite retarded.
Some forum members are butthurt because a fiction TV show called their favorite hobby 'illegal', and their arguement is that businesses who use it should be protected?
There is no one to sue them, and no reason to sue, much less no one to sue in the first place.
Also, I don't think the law recognizes defamation of a computer program.
There are companies that depend on the Bitcoin system - imagine that there was a TV show about someone 'illegally inventing Microsoft Windows'.
Microsoft is a registered company and trademark. Windows is a registered trademark and patent. You want to play with decentralized fire, you should expect to get burned.
If any business owner out there is stupid enough to accept a payment method associated with high amounts of fraud for example, they deserve to reap the rewards of public disapproval. It is very clear to me that very few of the members in this forum, especially in this thread, have ever run a healthy and successful business.
Ha ha - I see you get very ideologicaly frustrated about this idea. Relax.
Legally it will all depend on many details, and I am not a lawyer - but a protest about it would not do any harm, I can assure you.
