Only if you give them that power. The popular wisdom not to put all your eggs in one basket is still relevant.

You generally can't opt-out from your government, you definitely don't have to opt-in Google services.

How is that terrifying? I can access the web, use all the base protocols (email, etc) and store all my documents without having to rely upon Google. If I don't like/trust Google, I can easily migrate away. And, if enough people don't like it to make this "Kafka-esque nightmare" more than hyperbole, then the laws of private organizations will catch up and Google will either shape up or be no more.

This is almost the polar opposite of Kafka-esque.

Yes, of course, but they're not part of government. They're a company...

These Kafka-esque arguments are way over the top when applied to a private, profit seeking organization.

I completely agree, it's extremely hard. I can do without Google on my servers at all, and I'm happy about it. On my notebook, it's much harder. On a phone, it's almost impossible, if you have and Android phone. Google is bending over backwards to make you turn on more sensors and gather more data. I recently discovered it's enough to use the Gmail app once with a given e-mail address and it will happily turn on the location service (.i.e. phone tracking) for these accounts, even though you use a completely different account for your phone set up, including Google Play. They want to lay their hands on everything, it's so annoying.
