I am curious though how often the other shareholders are able to force the founders into a sale against their will. Is this common / documented? Seems doubtful that a Big Co would go into a talent acquisition if the talent wasn't on board.

It really depends on who owns how much stock. And if you the founder are disgruntled or not, if you sell, you may have to work for them for a year to get your money. Life's tough when you sell you soul to a VC.
