What happens when your key is simply stolen and posted online? They think that grants them the right to spy on all your passwords.
Where is the company, Flight Sim Labs Ltd., registered? It's difficult to find an address. They also removed info from their About page. From their posts it looks like they might be in the Netherlands.
Anyway, I'll contact the FBI and local authorities about this if I can find out what jurisdiction they're in and I hope others do the same. This crap is absolutely unacceptable.
