And I used an IBM System 360 in the mid-seventies. With punch cards. My first computer was a Sinclair ZX81, for which I wrote a little assembly code in addition to its native BASIC. I've programmed a VAX in FORTRAN. Until the last couple of desktop machines, I have always built my own from scratch. Today, there's no financial gain in doing so. There. Have we each established our "geek cred"? Not exactly what purpose that serves, when my original point still stands. This is not the place for OS Holy Wars.
