I only have a modicum of respect for this company after they butchered CentOS.
I’ve switched to Ubuntu too but my muscle memory is Redhat so still sometimes annoying- never got into Debian though
And yes, ClearCase does stuff that many alternatives to this days still has issues dealing with.
With ClearCase I already had object files caching across the build cluster without extra stuff, a nice graphical management tooling, and I never messed my view specification files, like I routinely need to fix my Git repos.
