> severely limits freedom of makers of end-user software Ironic for a "free" software license. It would be great if there was a license somewhere inbetween GPL and MIT: you'd be required to upstream (or make available) any changes you made to the parts of other people's code you're making use of, but not required to open your entire codebase.
