I read what I could and didn't find it overly persuasive. Obviously there must be evidence underlying these claims, but in the absence of that evidence a lot of it reads like one of those LSAT questions where you are supposed to spot the faulty logic. For example it just asserts that Google made it so everyone had to use their exchange and service, in almost those exact words ("had to") but there's nothing prior to that in the filing that supports this statement.
