Ubuntu founder doesn't "get" enterprise Linux
OK, that's not really true. Mark is a sharp guy, and gets open source as well, indeed, better, than most. But he's completely wrong on his criticism of Red Hat (which Greg of the Fedora Project shoots down). His basic point? Because RHEL is a closed binary, it's proprietary.
What Mark doesn't recognize - either out of pretence (meaning, he knows better but pretends otherwise) or out of ignorance (because Ubuntu isn't yet being used in the enterprise, so he doesn't yet know better) - is that the so-called closed binary is an important requirement for making Linux work in the data center, and across the enterprise, generally.
