Oh, I know. On a human level I can't blame anyone for making that choice. But then exiting with a big pile of cash while complaining about what Facebook is doing feels a bit... eh.

What else should he do? He took billions of $ along with a promise that he'll keep control. FB lied, so now he's leaving. I can't blame him here. Money can easily buy a bit of naïvety.

> What else should he do?

That really depends on what was stated in the terms of acquisition. At the most extreme sue to demerge.

But is that a fight he is willing to accept?

That'd be gutsy, but suing wouldn't have a chance unless he had promises in writing, which I doubt.

I'd rather have him do that then decide to stop complaining and give Facebook a pass now that he's one of them.

FB tripled in the last 4 years. So, a 4 year vesting period would have been a good thing for Koum!
