According to several reports Google stops updating older (<4.3) versions of Android. That includes not repairing safety issues.
That means that FairPhone needs to upgrade the OS in order to keep our phones ‘fair’ (i.e. usable a year after it’s introduction).
So please FP-team: now is the time!
I moved a post to an existing topic: Are the latest versions of Android really imporant for Fairphone(s)?
