* Mirko Boehm:
there is a simpler, less flattering explanation. More likely to be correct under Occam’s razor: Most of the ground work on this issue was done by Openforum Europe. Github is one of their member companies. FSFE piggy-backed on their work. Which means the interests of the free software community where much less present in the process than is commonly assumed here. This also explains the dopey wording on the Twitter message that exploded.
I found the implication disgusting that free software development depends on large-scale copyright infringement. I don't think the free software community has a significant problem in this area; we are generally pretty good at training new contributors in these matters. Most of us remove potentially copyright-infringing code proactively, even without notification from the copyright owner. Often, merely unclear licensing conditions are grounds for removal.
