Yes, that is the very reason that caused the split to X.org from XFree86.

When I went to XFree86's website, they said that it's still open source and free, so I was confused.
The crux of the matter (to my understanding) was not that it was going non-open source or non-free. The question was in a small amendment that the Xfree86 team added stating that all works that are compiled against their code must contain the Xfree86 Project copyright notice in the application. This was seen my many as breaking the "no further restrictions" clause of the GPL, therefore making linking a GPL project to Xfree86 a problem.
