The worst people are those who fight over the control of old free software projects, usually using DEI as a shield to a) establish a tyranny b) silence all opposition and c) secure their $250,000 jobs at Google, Facebook, Microsoft since they now have gotten rid of vast amounts of competition while pretending that they want to "grow the team".
This kind of behavior is not limited to software though. It was the Hippies of 1970 who slowly grew more powerful, and in the 1980s/1990s sold out entire manufacturing economies to Asia and Eastern Europe while pretending that The West is now a knowledge economy. And they got rich in the process of dumping IP while at the same time destroying local workers' livelihoods by replacing them with cheaper immigrants.
