You can argue that Canonical isn't upholding their end to provide security support, exactly what TFA is all about.
It's still a pretty basic reason businesses might calculate that Ubuntu is a good fit.
Agreed. Two weeks is pathetic. But, yes, I went over to Ubuntu because they were supposed to provide five years of security updated.
When I interviewed with them a couple of years ago, I got the sense there was a lot broken with their culture. It was the best choice back when RedHat/CentOS stopped providing long term security updates, but now that Rocky Linux is around, it’s getting to be time to jump ship again.
Also, almost every other time I upgrade Ubuntu, it's a shit show. I've seen the renaming of network interfaces, loss of default routes, systemd jobs that take several minutes to timeout... It's like rolling the dice. All the problems were fixable, but still an annoyance.
