1. If you were a startup would you want to do business with Silverlake having seen this?
2. If you were an exec working at a startup owned by Silverlake would you be reviewing your contract?
Dumb move. In business if both sides don't feel that there is a win for them in a deal, then the "winner" will shortly have very few people to do business with.
Always draw your curves, then plot your reading.
