It's not required to use all Google stuff (Score 1)

It's not required that you use all Google products and releases because Google is not a Supreme Being (contrary to my experiences). It's taken me a long time to realize this, but Google isn't infallible. They have made many mistakes and are similar to other businesses in that they sometimes just cave to market pressure. Google has released some excellent products and features, but that doesn't mean you must trust them blindly.
