If actually leaking anything does serious harm, then persuading people that leaking is a good idea - in order to create an atmosphere of leaking - is lying, because leaking is a bad idea. Goes the theory.

It may or may not follow that encouraging leaking is also a bad idea - this gets tricky depending on whether you expect the paranoia to prevent any actual uFAI projects, and whether you can use that to persuade people to commit to leaking instead.

Would you expect this approach to actually prevent rather than compromise every project? That's another argument, I guess, and one I haven't commented on yet.
