RHEL/CentOS are meant for servers/workstations aiming to run 24x7, and most of the instances might not event have GUI installed. I can understand why those problems were there as end user experience wasn't the priority. And you mentioned it was IT that updating the kernel, if I read it correctly, then it's the IT did not do their job properly as they did not test an update at all before rolling out. For 3rd party support, it's getting better, but as you mentioned, still a long way to go.
