Linux

To add nuance to my comment: I think that Linus mismanaged the conflict, and that this was a significant and avoidable factor in Marcan getting burned out. For an example of how Linus could have approached this instead: he could have publicly criticized both Marcan and Hellwig at the same time, rather than first publicly criticizing Marcan and then only after Marcan left publicly criticizing Hellwig for his own behavior. This probably would have made Marcan feel less picked on and less likely to have been burnt out. (Or maybe not; I do not claim to deal in certainties.)
