This is a great compilation, but it sort of misses the point. The problem isn't that Google owns all of the services we use. It's that someone owns them and even if you switch to a handful of independent services (which is a worse UX), someone else is snooping on you. Google's value proposition is that if you're inside the Google family of services, each service is made better due to having a unified analytics and user profiling. This is a double-edged sword:

  1. A single service has full visibility into your habits
  2. The upper bound for the efficacy of each service is higher.

Is this worth it to you? That's the question you should be asking yourself.
