To be clear, I don't subscribe to the idea of "Nothing to Hide." It's a bullshit argument. The reason why I'm asking this is because I want to be able to explain why it's bullshit. I don't like the fact that many people, including ones in my family, are willing giving up their right to privacy simply because they've become accustomed to convenience that modern technology has afforded them. I, myself, have been guilty of these but I'm actively taking steps to take back my privacy and potentially help others as well.
Bonus question: Many people will retort with things "Do you want criminals walking our streets?" or bring up an anecdote about how Flock, Ring or any other surveillance companies' cameras helped solve a crime or found a missing person. Flock themselves have a blog post series called #SolvedStories where they list so-called "success stories" about their cameras solving a case. Of course, I don't want criminals walking our streets and, sure, those stories might pull my heartstrings but what's the bigger picture?
Google now has the ability to see which lawmakers are talking to which lobbyists at what time thru geolocation. They can scan the contents of their inboxes and know what they are searching for. They can identify family members, associates, and do the same thing with them. They can know the username of any account that is ever signed up to any service using that Gmail address.
Imagine being a lawmaker and trying to crack down on Google when they know who you're talking to, where you are going, whay your constituents are saying to you, and what leverage points to squeeze. Even if you're squeaky clean, is your family, neighbor, etc?
They might not be doing it now. But they definitely could at any point.
