I considered bringing up Hans Reiser and didn't because it conflates what were already discussing with another issue: Support. Hans Reiser and his tiny company was the primary point of contact for support on ReiserFS. With him in prison no support was left for it, no new updates were coming. This doesn't invalidate the academic legitimacy of his work on "Dancing Trees", other technical topics definitely didn't prevent other file systems from using algorithm advances he came up with. Now stop mixing stuff that ought not to be mixed. Yes murderers, racists and xenophobes are horrible people, it doesn't make their every last statement wrong.
