> When someone comes along and tries to ship the same thing, improved, and break TOS to get exposure to CL users

Well, that's an incredibly euphemistic take on it, if nothing else. Let's see someone try to "get exposure to" (scrape) Facebook's user graph for a competing product and see how long that attempt would last. I don't understand how people can feel entitled to data that CL gathers: obviously they'd be protective of it as it's their secret sauce/crown jewels.
