Standard economic theory suggests that precise knowledge about your properties and preferences will, in the future, allow firms to extract the maximum profit from you, to your detriment. Google is already heavily investing the health sector, for example.

Not only does Google have a lot of broad data associated with your person, for example, any symptoms of disease you ever plugged into search, but we are also talking about an OS, which has absolute supremacy about anything you do on that computer.

That is why we should care, and that is why a comparision even to amazon or facebook is not accurate here. In this particular case, the breadth and depth of the possibilities to get data about you are unusual.

And keep in mind we are arguing about an OS that is technically not even open-source.

Everyone knows the consequences of surveillance, there is no need to wait for consequences to be concerned. The casual disregard and lack of appreciation of the values that make modern societies possible is concerning.

Hand waving away surveillance infrastructure and seeking to normalize invasive surveillance is in the interest of companies like Google who profit from it, but for citizens to be blase suggests a reckless disregard of historical record and the societies they live in.

Of course, the obvious solution is to run a good Linux distro or OpenBSD, but frankly it's hard to live with purely just Linux for me. ChromeOS has the advantage of things like near perfect High DPI support.
