I sympathize much with your stance on Facebook. However, I'm curious, what keeps Google from being an adversary in your perspective?
If you visit a country where you don't speak the native language, Google maps will help navigate through the country or city. Even help with public transport. Youtube helps with DIY videos or programming talks. I wouldn't have discovered Khan academy without google. And before you say DuckDuckGo is an alternative, i have DuckDuckGo installed and i prefix my query with "!g" around 90% of the time.
