Good, megacorps is last thing this world need.

Science the sh*t out of it

Gentus Linux comes to mind, obscure distro based on Red Hat (not RHEL mind You) released by now forgotten ABIT, a motherboard manufacturer. I was daily driving it as teenager back in 2001 for couple of weeks until I learned by trial and error how to get windows 98 installed back. Another one would be Mandrake Linux which I was dual booting couple years later.
