Because Linux not an OS. The flagship OSS OS is Ubuntu, and it's mostly pretty stable. But OSS inherently implies the ability to make your own OS that's different from someone else's OS, so a bunch of people did just that.
Is it the flagship of Linux Distros right now? I though RHEL (The most common to see paid software package for) would be up there, along side its offshoots of Rocky / Fedora
Ubuntu still suffers the same kind of breakage though. You can't take an moderately complex GUI application that was built on ubuntu 2014 and run it on the latest version. Heck, there's a good chance you can't even build it on the newer version without needing to update it somehow. It's a property of the library ecosystem around linux, not the behaviour of a given distro.
(OK, I have some experience with vendors where their latest month-old release has an distro support release where the most up-to-date option is still 6 months past EOL, and I have managed to hack something together which will get them to work on the newer release, but it's extremely painful and very much not what either the distros or the software vendors want to support)
