The author is trying to use that relationship to stress a point which stands no matter whether the founder is related to Google founder or not. Take that piece of information out and the point that the author is making still stands. Google has showed us that by luring people to share their private information, it is possible to sell your users eventually. Now you don't have to be related to a Google founder to learn and use that business model. If there was any other company that followed the same practice and didn't explicitly allow me to own my data and delete it from their databases I'd be worried about that company as well. No matter whether they are related to Google or not. The relationship to Google just make me extra worried because of the history of Google.
