Yea, I have a lot less faith in the explicitly-unethical Facebook and its leadership than in Google, and that's been the case pretty much since Facebook came on the scene. But how principled the founders are is only one part of the picture, and Google just has the potential to be a lot scarier. People change, companies outlive tight control by individual people, and explicitly-evil actors with armies force companies to do things or compromise their systems (this already happened to some degree a few years ago). I don't really understand why HN goes on and on about how social media is inevitable and you're just a victim of its use. It's pretty easy to drop Facebook and pay a pretty trivial cost. Avoiding Google products, on the other hand, requires a sustained attempt in a dozen different product areas to use usually-inferior products. It's not impossible, but you pay a fairly hefty cost, to the point that most people don't bother. As you mention, they also have a lot finer grained data about what you actually do, as opposed to Facebook mostly knowing what you care to share.
