The other question is how much innovation is the result of spite? The professor who told someone they're never going to amount to anything, the business person that told someone "that's never going to work".
Butterfield [1] started a company to develop a game, but during their interactions the employees created some photo sharing code which ended up as Flicker, which he then sold off. Butterfield then started another company to develop a game, but to make internal company communications more efficient they developed some chat software which ended up as Slack, which he then sold off.
I have not heard if Butterfield has started a third company to develop a video game.

You can still hear the music written for the game 'glitch' if you join a slack audio room with nobody else in it.
