I would fit your definition of fanatic and I have a friend who does too. The only google service we still use is YouTube because that’s the hardest one to replace entirely unless you want to cut yourself from a lot of very interesting and entertaining content. Otherwise it’s not so hard. Gmail is hardly the best offering on the market, Apple Maps are good enough for most tasks (Google Maps still has better POI data sadly), etc. You don’t need to be a “fanatic” to de-googleify your life, even if only partially.
