Obviously I know there are business cases for this sort of stuff and whatnot generally, but as a kid first learning what LTS meant, I've always appreciated Ubuntu for this.
However, it is the only distro that came very close to unifying the desktop, mobile, server and embedded application spaces. In a way it greatly impacted how people approached designs, as the classic heterogeneous build circus approaches often became a trivial role assignment.
It takes a bit of work to get the current builds "usable", but the FOSS curse now tightly couples release cycles to specific application compatibility versions. Or put another way... everything is perpetually Beta eventually, or becomes a statically linked abomination. This is the very real consequence of the second system effect: https://en.wikipedia.org/wiki/Second-system_effect
At least they haven't jammed an AI search indexing snitch into their interface... yet...
Cheers =)
