I've long held as an author (lets say entirely amateur simply to keep it simple), that I literally do not care, and in fact encourage people to take my stuff and run with it. As a practical matter I draw the line at slapping your name on my actual words or monetizing my actual words, but beyond that I'd be flattered if someone wanted something I had created enough to post it on a wiki or a pirating site.
I suppose if someone chopped up something I wrote in order to misrepresent it, to present it, or me, in some malicious fashion that is clearly not evident in context, I'd be upset, at least as much as if they slapped their name on my actual words (I am drawing a distinction for derivative works. If someone wants to write fiction set in Haven (as posted in on this forum), knock yourselves out, you can even quote me here: I don't claim any right to what you write with my creations.
I suppose, philosophically, I've had reason to reconsider my stance based on an interesting video essay on the tragedy of the commons and the value of strong IP laws in promoting and creating works, but I'm pretty comfortable with where I've drawn my line in the sand, despite being way, way out there in 'its all free man!' territory compared to most folks.
Huh. Who knew I was some sort of radical extremist?
