@plexus yes. It can be found everywhere and those internal enemies or infights are the worst. And it's known. Known by marketing agencies who support or put people into communities to be "the better" foo. It's documented in court cases. In my country, the "green party" was an accident(!) of such an agency which was hired by the arms industry to cover an arms deal. Tell someone about self hosting stuff and they will demand you have Cisco certificates, otherwise your are not "pro enough".
