Anti-competition laws (in the US at least) only take effect where a company 1. has a monopoly or near-monopoly in a market and then 2. abuses that position to keep out or disadvantage competitors.

The laws don't apply to Google here because there's significant competition (SkyDrive, iCloud, Dropbox and others) so no monopoly. And Google is also fine in markets like search where they are the dominant player unless they start doing dumb things like penalising companies for advertising on other search engines.
