Redhat stands to lose their defacto control over X after the XLibre fork so they have to stop trying to kill it. Who would have thought that competition would make things better for everyone?
I doubt they care too much. They probably just have customers with applications stuck on a legacy window system. And they pay for that maintenance.
Alan Coopersmith works at Oracle, on Solaris. I don't know of any effort to use Wayland on Solaris, so maintaining X really is their only option.
OTOH, RedHat seems happy to let X die.
