That's why OSS is not about the contents of more restrictive licences (as you say, copyleft is a good example), but about the broadest definition that applies to all of them. More specialised sub-types can have more conditions, but then we should speak about those sub-types directly.

I make this point because it causes confusion. Saying "my OSS project is being run by others for money and I get none of it" is confusing, as it uses the supertype. Using the subtype is clearer, and even self-explanatory: "my project I licenced so others can make money from it while giving me none is being run by others to make money from it and I get none".

That may be a bad situation, but at least the reasons are now clear.
