Hey even I use Linux daily.

Actually, I’m not really sure why “even I” should be shocking. I write code for a living. Surely I should be using Linux once in a while.

Anyway RHEL is probably the only Linux distro I can think of that costs money and comes with support. The major cloud providers sometimes have their own Linux distros they use as well (looking at you, Amazon) and you can argue they are selling Linux, but not as directly as RHEL does.
