On "what is happening here". The legal rules of licensing and copyright are basically a pita for everyone and nearly impossible to apply them at scale. So everyone in this field, IP holders and users have all tacitly agreed on a social contract that is quite different from the reality of the law. This small niche of society is small enough and poor enough that the law have not had to catch up to it yet. This is a ... typical thing to happen. If it grows big enough, the law may catch up. Or the social contract may have to catch up. Or more probably a mix. This is usually painful. Consider that Free and Open Source Licences are kind of a hack to paper over that gap. It has been enough so far to keep the two worlds from colliding too hard. But it is a fundamentally limited way to bridge it.
