I don't think this is a comprehensive list. I don't know what the exact requirements are but based on the domain it seems related to Google Enterprise policies.
is fairphone an android partner? i thought they shipped some sort of de-googled AOSP-based operating system
(it’s just not a very good phone for the price, but they try to push updates as long as possible, from what I heard)
edit: yep still getting updates 7 years later
