The worst.

But is the problem in the licences themselves or in the legal system who made us having to fight against an army of Jeff Besos's lawyers to make them respected?

If the open-source/creative commons/whatever is owned by someone big enough, it is respected. Hatsune Miklu is a good example.

The problem is in the copyright laws that make wealthy organizations solely wield the intellectual property rights. This allows some non-profits to defend some individuals' rights, but on the whole it mostly benefits for-profit businesses.

Is there anything in this world that do not mostly benefit the for-profit business?

Local direct cooperation (wink wink @Spencer ) but otherwise the deck is heavily stacked in their favor indeed. What I meant is that there is no inherent problem with the mostly free licenses, rather with intellectual property (even even property at all) in the first place.
