Red Hat stops all upstream and downstream work on desktop Bluetooth, multimedia applications (namely totem, rhythmbox and sound-juicer) and libfprint/fprintd
RedHats focus is on Enterprise Linux, Openshift, AWX, etc.
Are they even a “competitor” in enterprise Linux desktop? Enterprise Linux servers, sure, and I suppose a good number of orgs who don’t want to deal with dissimilar “user” distros, but I’d think Canonical would have enterprise desktop Linux pretty much sealed by now.
I've had a couple jobs with RHEL workstations, and the university I went to had RHEL workstations too. Not sure what their market share is compared to canonical, but they definitely have a bunch of deployments on desktop.
This is a fair point, but I don’t think Linux would be nearly as adopted in the business world without that branding. It’d be some fringe hobbyist thing and BSD would probably have become the server operating system of choice.
