Note that if you read carefully, the guy was actively supported by the U.S. at the time he prepared the "revolution." He claims he's disappointed by Muslim Brotherhood gaining power, but it was he who even helped them, he being then just "an activist" and they being a real "political group":

"I negotiated agreements between activists and political groups like the Muslim Brotherhood."

Note also that the Muslim Brotherhood was actively "the choice" of the U.S. at the time of the revolution. Now I'll quote the author once again as he describes the power struggle between the military and the Muslim Brotherhood:

"The election represented Egyptian politics since the revolution: a power struggle between military dictators and religious fanatics. And the Muslim Brotherhood—whose religiosity, I believe, is a trojan horse for pure political ambition—treated activists just as harshly as the military."

I personally don't believe the religion of Muslim Brotherhood is "a trojan horse," it's where they get the the goals of their political activity:

"The Brotherhood's English language website describes the principles of the Muslim Brotherhood as including firstly the introduction of the Islamic Sharia as "the basis for controlling the affairs of state and society" and secondly, work to unify "Islamic countries and states, mainly among the Arab states, and liberating them from foreign imperialism""
