That's a bit naive though. People can always find ways to hurt you - it's a very asymmetric fight. With a complex application such as Basecamp, you can't really put everything behind a cdn.
That's why I actually think that their thrust on pursuing the legal/FBI route is a good one, especially if they achieve any success there. This extortion/racket is indeed criminal and not tolerable. It would be good to catch the racketeers and make an example of them.
