Also, what if you can't sell? Selling is at their discretion. They can prevent you from selling some of your so-called "equity" to keep you on their leash as long as they want.
Apologies in advance, my comment does not add to progressing the thread at all.
I was just in the middle of eating a delicious raspberry danish - I read your comment and just about lol'd it all over my keyboard and wall.
The last thing I would do if I had a bunch of equity is screw with a company with some of the most sought after technology in the world. There is a team of lawyers waiting and foaming at the mouth to take everything from you and not bat an eye about it. This seems very obvious.
