It's not just successful companies though. There is a bit of ego necessary in a founder that makes them think their idea or their implementation of a thing is better so that it needs to be its own company. Sometimes though they even get caught up in their own reality distortion fields with obviously bad ideas or ideas implemented badly due to their own arrogance that ultimately fails.
If I thought I had a great idea, I would want people to try to poke holes in it. Yet founders often universally seem to be the incredibly sensitive and insecure about their idea.
That is...not a pretty picture. We desperately need someone else at the helm of OpenAI.
