What Google services do the Google Pixel phones require using? Or can they be used without using Google products?
For example, do they require using a Google account? If so, do they require using the Google Play Store? What about Google Drive? Do they force syncing contacts and calendars to Google servers?
Can all the Google apps be disabled on them?
When answering please specify if your answer applies to the original Pixel or the Pixel 2, or (if you know) both.
