People can reasonably agree on what "Open Source" means. Once you start trying to define "bad guys" and exclude them, you will get dozens of incompatible definitions and no consensus, and as a result, you'll have numerous incompatible ecosystems rather than one.

"Open Source" isn't perfect, not by any means. But any purported replacement for it has to be so obviously better that people are willing to switch and build consensus on the replacement.
