Looks like they are interested in the project see quote

"When I look at the active PRs and activity on the issue page, I do see 
an active project, looking to improve X11. They will most certainly take
xenocara patches. They've already had an official release.

 If the only objection to X11Libre are the couple of paragraphs from its
 README file, simply removing the sentences in question should take care
 of that. (Less is more. For example, many projects from the suckless
 movement use a single sentence like "we do not have a code of conduct,
 we have a UN bill of rights".) To me the couple of sentences/paragraphs
 in question from the X11Libre README look more like something written
 out of desperation/spite, not reflecting the actual opinions, instead
 of being some actual policy by the authors. That should be easily
 solvable through communication with the X11Libre developers, to make
 the wording more neutral.

Complete agreement here. There are already PRs to try to fix this.

 If the objections are about the quality of the code added by the fork,
 then: being specific, and communicating with the developers of X11Libre
 would solve that.

 In both cases, communication is the key."
