Nobody is claiming ownership over Xorg. That's ridiculous. If anything, it's the people who are deliberately trying to "kill" it. Some people simply want to keep working on it, many people still want to keep using it, yet they're being forced not to by egomaniacal children.

The job of distro maintainers is to make software accessible for their users. It's not to provide support for the software, nor to fix its bugs. Choosing to not package a specific software is user hostile.
