Not that you didn’t make the right call, but many of the longer software update “confirmations” (obviously they’re only worth something if they commit to that) happened around that time. Almost any android phone didn’t have more than a couple years of support, until very recently. Naturally, no brand is going to backtrack that far, especially for a completely new phone concept that they knew was going to have issues.

Something can be said about that on its own, but first gen devices always carry first gen issues, and the news (both people and articles) of the time was very vocal about such. Personally I’m on the side of providing long software support, but not extending to hardware (in niche cases).
