People publish things for all sorts of reasons, sure, but the main one is that they think the information has value. Whether some corporation profits from it is completely irrelevant, the data doesn’t care who benefits. The author doesn’t matter either, what matters is the information itself. Licenses just try to put fences around what should be free, and most of the time they only get in the way. People can follow them or ignore them, and life goes on. The scene understands that better than anyone else. It’s the purest form of the web: information shared for its own sake, without permission, limits, or fake moral theater.
