Adding on, if Google can show consistent support for prolong period to their own products then it might help restore confidence.
Otherwise, the past 10 years since Nexus series has proven that Google will terminate products/services without much thoughts.
To be honest, even a simple feature like restricting access to notification centre in lock screen (unless unlocked) which in my opinion is a basic feature for security, is not available on Pixel phones. How much confidence does existing and potential users have with Google's products.
