I’d like to agree with you that she got what she deserves, but she appears to have made it out of the building as a billionaire with the power to ruin a generation of schoolchildren.

Indeed, having recently faced Dropbox Space Race promotion expiring. But 2 years I have to say is plenty of time to not worry about it. It's a good deal, because by then, there ought to be a cheaper price than the current ones and there would most likely be a deal for those who signed up for those 2 years.
