I bet you if we added up all the time *****ing about the cobra dongle, we'd have already figured out how to do what they do. I'd also argue that figuring out how they do it would be easier than trying to crack the dongle.
If no one is willing to invest the time (strange that we have time to ***** though) then I don't think anyone has the right to complain if they charge money or not. They put in the effort (even if it wasn't their code to start) did you? Sure you can argue this but I bet over 90% of the people complaining are more or less pissed that they can't pirate.
BTW, I'm still not going to buy this.
