Google's Terms of Service and Privacy Statement motivated me to give up over 3,000 Google+ Friends, and to stop using the Google search engine and the rest of their products, attractive as they were. Finding alternatives is definitely do-able.
A year ago, I divorced Google. In any divorce, friends go with both sides. Most friends went with Google, but a few stayed with me. I'm in a much happier place. It can be done. The co-dependency is over.
