Atari
When Warner bought Atari, the first thing they did was cancel the bonus to any programmer who authored a marketable game. The bonus was $100,000. Warner was accustom to handling actors so they thought they didn't need to pay bonus to programmers. After all, where they not paid a salary to write games.
The programmers on hearing about the cancellation, quit and went to work for Electronic Arts. Atari went bankrupted and EA flourished.
