Steam

Gabe Newell is a man with a red button on his desk that, if pressed, will immediately grant him 11 figures to distribute as he pleases. It's labeled "sell Valve to Microsoft/go public". Newell hasn't pressed the button. Newell and his employees are satisfied with "making shitloads of money" and don't need to "make more shitloads than last year, forever".

I can reasonably say that Newell probably won't press that button during his lifetime. Similarly, I'd trust anyone with that button to hold onto it no matter what, because "if it's getting pressed, it should be me pressing it."

Once Newell dies, many bets are off. That's a really, really tempting button to press. There are very few humans likely to not press it.
