Internal proprietary chat vs async public discussion
If you're seeing this linked because you used an internal-to-RH proprietary realtime chat system,
please consider instead interacting on an asynchronous, public channel such as a GitHub issue,
Bugzilla (but uncheck the "Private bug" bits), or public mailing list like fedora-devel@
or centos-devel. Another good alternative is https://discussion.fedoraproject.org/
You'll see it said that Red Hat is an enterprise software company with a FOSS development model.
