The interpretation is simple and the complete opposite of "I have the freedom to kill you".

The software creator (human or AI) must give the user of its software the same freedoms it has received.

If it has received the freedom to view the original, readable, source code, then users should have the freedom to view the original, readable, source code.

If it has received the freedom to modify the source code, then users should have the freedom to modify the source code.

Etc.

It's not hard to follow for people who want to do the moral thing.

It's VERY hard to follow for people who want to make money (and ideally lots of it, very quickly).
