I'm no lawyer but logically speaking the antitrust allegations against Google don't seem like they'll amount to much, firstly the notion of having the government dictate what goes in your app/website doesn't sound right nor legal. And there is the blatantly self serving demands from competitor alleging consumer harm; they either want to be guaranteed prominent placement among Google’s results or they want Google to only feature links, and only links to the end of time, meaning they don't want them to innovate and would like them to offer an inferior product, and given that people have had a taste of Siri for example, the notion that search engines must only serve links has dissipated.
There is also the small detail of Google being free, and has virtually no-lockin and anything they offer has an equivalent offered by somebody else. And last time I checked they didn't lack in competitors, so why is the government essentially also competing against Google. The whole thing seems like a result of a major political malfunction.
