content: I follow this rule. The last two services of Google that I enjoy are Youtube and Android (without Google Play or a Google profile at all). Once I discovered that they track your browsing history and they sneakily maintain log-ins after you close the browser window, I decided to call it quits. I switched to Yandex for email and F-Droid for Android software. I do wonder though, does Yandex track people as much as Google does? Yandex certainly isn't as prevalent on the web as Google is, which would make it at least more difficult if they do... and Yandex is from Russia, which AFAIK is not one of the five eyes. I would not use an American email service now that we know what we know.
