We don’t need to presume anything, OP can speak for themselves.

Sure they can! Until they do, there’s my helpful take for the meantime.
But don’t take my word for it, you could also piece together their intent by them thanking all the other helpful responses in this thread that happen to elaborate on legal obligations 😄

What do you mean by this?

Many things in life come with legal, moral or financial requirements and obligations. The OP presumably wishes to know whether there are any that they might not yet have considered in their situation.

I personally nerver really understood the whole semantics debate that always unfolds in situations like this. What does it matter if a piece of software is truly libre or how it is licensed as long as the source code is available? Respecting a license is a choice. If you have the code you can fork it. Whether it’s libre or not only influences your ability to put your real name under the fork, doesn’t it?
