When does the Prime Directive cease to apply?
I have been wondering about this recently. Am I right in thinking that the Prime Directive refers to civilisations that are pre-warp, but once a world achieves warp technology it no longer applies?
Is there unlimited sharing of technologies once a world reaches this level?
The Vulcans did not follow this after first contact, but of course that was pre-Federation. However, as members of the Federation they likely would have to adopt any policies regarding the sharing of technologies that were voted in.
