Essentially yes. While weak copyleft would be fine for the use cases i have seen, the distinction and the licenses have yet to be tested in a EU court.
As a a consequence there are a numbers of legal options on the matter and as a consequence to that, it is a very hard no from most compliance deps i have seen
Do you really mean copyleft, or do you mean the GPL family?
What about MPL and EUPL? I have heard the legal issues with GPL, never for MPL and EUPL.
