>A-chan releases own crap under MPL>B-chan forks it and adds GPL code while preserving MPL headers but by FSF reasoning the MPL code is already dual-loicenced under GPL; however the changes to MPL code made by B-chan are happily ported back to A-chan's project>C-chan forks B-chan's fork, removes MPL from A-chan's code, modifies it and releases the changes, including those made to A-chan's code, under GPL only>A-chan commits suicide because GNU weenies are cunts
