Also LTS means "95% of the developers left for the newer version because on open source projects no one can be forced to work on legacy applications like in business world".
Good luck with that. I tried to go on with the Ubuntu's LTS once, and the logic definitely doesn't work. Bugs, even major ones, just pile up faster than the remaining couple developers can fix, and it's was too painful of an experience to repeat. Ubuntu LTS has shelf life of 6-12 months unless if you start paying. Which is unfortunate.

Yep. I see this a lot in the scientific world. Clusters and other high-performance hardware run old versions of Scientific Linux or CentOS (because they are well-supported and the bugs are known). However, a lot of open source project (e.g. in machine learning) expect you to run the latest Ubuntu or OS X version. Result: you usually end up hand-compiling large amounts of software, manually adding '-I' and '-L' flags to oddball build systems that don't pick up CFLAGS or LDFLAGS correctly.
Nobody cares about backwards compatibility, everyone wants the new toys.
I want "something", that something being backwards compatibility and long-term support, for $100-150. Can I get it from Ubuntu or any other Linux/Unix? I sure as hell get it from Microsoft.
