In one way, but the comparably aged Nexus 5X at least got updated to Android 8.1 while the Fairphone 2 is still on 7.1
The Fairphone 2 can run Android 9 via LineageOS. The official versions (the one with and the one without OpenGapps) still get security updates. Can you say the same about Nexus 5X with Android 8.1?
