That's na├»ve IMO.  That's like saying that nobody cares about your email communications or other data.  Of course they care.  It's part of who you are and to advertisers and corporations, that's very appealing.  I understand why they send it to "the cloud" but to pretend like that's not something that corporations would be interested in storing and mining is just wrong (that's like saying, well, you're one in a hundred million, so no one cares what you're searching in Google... which isn't' true... you're a small portion of the pie but they very much care to know what you're searching for and how you're using the Internet).
