But too often ill-advised except when “mission critical” 3rd party software has not been ported to their current distro.
Edit added: user churn consumes resources and is often a substitute for actually learning how to take best advantage of support resources and how
linux works. I advise new users to chose a distro that colleagues/friends/family use so they can get eyes on support for problems.
Newer kernels often have issues with older/uncommon hardware, but also improved security. Spending a small amount of a USB wifi or sound dongle may get past a problem with older hardware, while reverting to a different distro that works because it still supports old hardware just means the hardware won’t work when the distro moves to a newer kernel.
From a typical user’s viewpoint, it is difficult to identify the reason for a problem and find out what work has already been done to fix it. Too many users jump on a problem report without understanding that their problem is different, so will start looking at other distros when the 1st “fix” fails.
