Probably because they could sue them for not keeping their word.
Unless those funds were placed in an escrow account, I would have assumed that claim held no water.
There's a reason corporations almost always settle lawsuits (if they aren't dismissed).

Litigation is a rich man's game. Companies almost always have more resources to dedicate to litigation than individual employees, especially if those individual employees have been laid off and are now without an income.
The company knows this, the employees know this, the company knows the employees know this, and vice-versa.
Okay, so how many nights until the blue-eyed employees all leave the company? :p
You can't say, "Well, we hired a new CEO, so all those old agreements are null and void."
