No,
Lots of us run "legacy" OSes e.g. old Mac kit, amount of RAM available limits what OS version you can upgarde to, but why bin a working machine just because it cannot run the latest OS? .. Yes, users could use Linux instead, but they might want to stay on a Mac OS because they like it
One of the good points about open source is not just pandering to the latest & greatest software / hardware, but allowing older stuff to limp along a while longer (we don't all have cash to burn on buying new kit as other priorities come first, a bit of new shiny is low on Maslow's hierarchy of needs)
Biting the hand that feeds IT
