> I'm no fan of Uber, but if there are LEOs trying to use your product fraudulently (e.g. fake data, ordering an Uber not for a ride but to impound cars), doesn't it make sense to try and stop this sort of operation?

If it's actually fraudulent, then, yes, you should stop it by suing and getting an injunction against the illegal government action.

If it's just enforcing the law that you are breaking, maybe you should quit breaking the law rather than engaging in elaborate technical means to conceal the violation, and expecting that won't cause additional problems when it is discovered.
