The US-Based NGO’s financed the revolutionaries, and Mubarak was an impediment to The Obama Administrations plan for a “Greater Middle East” that isolates Isreal. (more recently rebranded to the milder-sounding “New Middle East.)
Mubarak was staunchly opposed to Obama policies on Iran and how to deal with its nuclear program, on Obama policies towards the Persian Gulf states, to Syria and to Lebanon as well as to the Palestinians.
He was a formidable thorn in the larger Radical Liberal agenda for the entire region. he had to be removed for the agenda of the Radical Islamists around Obama to go forward.
Obama (like the rest of the left) has a default anti-Israel, anti-American bias, especially when it comes to dark skinned savages who hate the West.
Obama wasn't necessarily "pro Muslim Brotherhood", just biased (and stupid) enough to think political engagement could change them, particularly if we withdrew support from a pro-American dictatorship.
Soros is just a funder of obnoxious NGO's having little or no power outside the US or Western Europe: it's only in the decadent West that people are actually naive enough to think Twitter can overthrow a government. As soon as the Brotherhood took power, the left of center groups funded by Soros were shoved aside, as such useful idiots usually are. Having had a taste of incipient sharia lunacy, a lot of their members are now siding with the new military government.
After the election that Morsi allegedly won, the Egyptian court refused to ratify the results for some reasons (fraud?) and days ensued where things were in limbo while they tried to determine who won. Instead of letting the Egyptians sort things out, the MB-aligned obama administration spoke out and pressured them to decide in Morsis favor.
No one talks about this tidbit anymore but that is how I remember things happened.
