The part you left out of the quote:

> Versions of XFree86 up to and including some release candidates for 4.4.0 were under the MIT License, a permissive, non-copyleft free software license. In February 2004, XFree86 4.4 was released with a change to the XFree86 license, by adding a credit clause,[23] similar to that in the original BSD license,[24] but broader in scope.

The old license wasn't copyleft. Copyleft didn't cause the fork.
