It's not a matter what I want to do, but a matter of what needs to be done to weed out all the fraudulent/dishonest/incompetent companies associated with bitcoin, which is almost all of them. And it is a matter of justice being served. Are you okay with a dishonest company handling something you believe in?
So stop giving them money. Stop giving them BTC. When "companies" can't follow the established standards, don't use their services. Don't order their products. When they make it clear they're scamming, either willfully or out of sheer lack of ability, don't use them. Even if there's no convenient alternative yet.
No matter how many lawsuits are discussed, no matter how many fantasies of vengeance are born, this shit will continue (and likely multiply further) until people stop enabling the clueless to wander in and wildly mishandle things.
