This is a really low bar. Enough Android device makers never provide updates. Got a Nexus One a few years ago, Google updated it for a grand total of 13 months before deciding it was "too old". Of course I didn't get the Nexus One until most of the way through that time period so my Google phone was updated for perhaps six months, not exactly a great user experiance.

18 months is far too little, especially if you do not buy a phone on day one.
I don't think Android TV has ever gotten much love either.
Glass went from monthly updates to completely unsupported, practically overnight. That actually was being openly sold on the Play Store for a while too.
I'm not saying they haven't been on the ball with most of their mainstream products, I'm just saying you should bear in mind that they've let plenty of their failures just die on the table too.
