> Remember: the whole point of the GPL is to reject copyright, and that specifically means lots of corporate freeloading, because the whole point of copyright is to stop corporate freeloading
I don't think this is true. My understanding (which could be flawed) is that the whole point of the GPL is to weaponize copyright in order to guarantee freedoms, not to reject it (a subtle but important distinction).
Also the whole point of copyright doesn't seem to be to stop corporate freeloading, though that is of course part of it. It's point is to ensure that the original creator has rights to benefit from the work, whether that means getting stolen from by a huge corporation or stolen from by teenagers passing memes over the internet, or adapted by an individual/sole proprietor as part of some larger work, etc. My guess is we probably agree on this part and the debate is probably over semantics (i.e. you might have meant "business in general" by "corporate" rather than specific corporations).
