I agree that this is probably the right answer. Unfortunately, it's a difficult business model to pursue and open source may not be able to solve it. I look at this like I look at Linux versus Windows/OS X (as I type on my MBA next to my work Linux laptop): Open source may provide an alternative that, for a certain class of people, is every bit as good as the commercial mainstream; but for Joe Sixpack and Molly Mall, using such a solution doesn't even factor into their consciousness. It's not that it isn't good enough; it's that it doesn't even exist on their plane of existence. I've spent a reasonable amount of time thinking about this (as a side-thread from a previous start-up I was involved with), and I have yet to come up with a combination that satisfies my preferences for data privacy and ownership with "normal people's" preferences for ease of use. Unless a catastrophic failure occurs (Facebook crashes and loses everything), I don't think people will realize there might be better solutions.
