The decision to use the MIT License is not without its critics

I believe the point being gotten at here is that, in all three cases, it wasn't licensing alone that drove the community to the better fork, but a desire to distance themselves from people being obnoxious in other ways that they could only get away with because the law does not outright forbid it.

XFree86 had them (their website pretends they're the only game in town to this day), anyone who's been a reader here long enough remembers OpenOffice *definitely* had one, and in coreutils' case the FSF has a wannabe BSA Auditor loose on the internet trying to shut down the competition through concern trolling.
