Okay but that has no relevance at all to what the comment you were replying to was about. Companies contracted by the government and DOD specifically to create rockets are guaranteed to be covered by ITAR. Meaning open sourcing them would be impossible, regardless of the first amendment or anything else.

There’s a massive massive difference between the software for a DOD contracted rocket like SpaceX makes, and hobbyist rocketry.

In the U.S., you can build rockets all day long, they cannot be guided.

You’d have to convince the feds it was never designed to be a weapon. Good luck with that.
