It’s about interference with non-Federation governments and cultures in general. The Prime Directive forbids mucking about with Romulan politics, for instance. Worf gets away with a lot of things that would violate the Prime Directive in regards to the Klingon Government because he has dual citizenship and is a member of Klingon nobility.
The ban on contact with pre-warp civilizations is also more specifically uncontacted pre-warp civilizations (you can chat with them if they’re already buying Romulan ale from the Ferengi because the damage has already been done) and more generally pre-interstellar civilizations (warp drive is the usual way a civilization becomes interstellar, but there are alternative methods).
