> I've never seen an Android that would get updates for more than 2 years (can anyone beat this with 3?)

That depends: Are you looking for updates to the new version or security updates?

Android One program gives you two years of regular updates, plus an additional year of security updates. My Nexus 5X received two major updates (from 6.0 to 8.0), but I kept using it until the security updates stopped. That's essentially three years of support.

Ok that's a good start for the Android world... But it still won't convince me to buy another phone that is based on this OS.

My crappy old iPhone 5s is _still_ supported today - not just security patches but the OS as well. While providers like fairphone do a good job with their supply chain I'm afraid the longevity of this phone is still better for the environment.
