exactly, if your on at@t you will wait damn near a year to get an update. I had jelly bean on my note1 a good 10 months before the OTA. Google hasn't done crap with the software besides bug fixes and small crap for 2 years now. Also don't forget its not Google that brings you all those features that the LG's and sammys have its the software they add to googles. Pure ASOP is very basic, yes you can build a kernel or flash one to get things like tap to wake and things like that on AOSP but all that is done by 3rd party devs not Google.
Just like apple peaked 2 years ago android has done the same and dev is all but at a standstill for both. WP can be compared to the early days of IOS so stick with it, WP as a lot more to come.
But wait apple gets small updates all the time, yes they do, exploit patches is all they are.
