> During a hostile takeover, someone buys 51% of the shares. They then elect a board of people who will approve whatever they want.

This is confusing. During the TWTR discussions, one that regularly came out is the importance of a board's fiduciary duty. Buying 51% doesn't let you take the company private, and merging at 50% of the price seems like a monumentally indefensible decision, especially when it is with the 51% holders company. I find it hard to believe you can get away with that.
