"Surely this is similar to someone conatcting a high street store and saying they know a way of disabling their shutters. They will not disable their shutters but will tell everyone how to do it if the store doesn't pay up."

Yes but (to continue the analogy) he stood outside the shop shouting to everyone how to disable the shutters, even the security guards (LinkedIn) heard how to do it and fixed the shutters accordingly.

What he didnt do was whisper to the baker on how to do it.
