@mark @lauren For a very large portion of people who produce things meant to be free for the reading/use of others (free software but also lots of analogous things), the compensation we're getting is standing to speak as a trusted source on the matters, things which we usually have some deep care that they're done right or at least in a way we find agreeable.
When it's just taken without attribution - or even worse, with attribution, but adulterated with all sorts of wrong stuff mixed in - that's completely negated and the social contract by which the sharing took place is broken.
