Don't forget the development issues. Last I read up on this was several years ago, so things may have changed, but:
It's open source, but it's entirely controlled by a handful of people who work for RedHat, and they don't publish any of their communications about development nor any supporting material like code documentation. It's a massive complicated codebase and they've made no effort to make it accessible, nor do they allow contributions from anyone outside the RedHat team, so it remains a closed black box controlled by a private, for profit corporation.

It's open source in the worst way possible.
