If that's your definition of a lifespan, "max 2 years" is absolutely not true. Android has two types of support: new major releases and security patches.
An average Android usually supports new major Android releases for 2 years, but security patches usually go longer. Not as long as an iPhone, but more like 3-5 years.
iPhone 6s (released September 2015) - ~ 8 years and going
Nexus 5X & Nexus 6P (released September 2015) - last update January 2019 [1] ~ 2.25 years
Pixel & Pixel XL (released October 2016) - 2019 (can't find a good reference) ~ 3 years
Pixel 2 (released October 2017) - December 2020 [2] ~ 3.3 years
> Not as long as an iPhone, but more like 3-5 years.
Pixels starting from 6 -> 5 years.
Recent Samsungs -> 4 years.
Fairphone 2 (Dec 2015) -> lost support last month.
Things have improved since Nexus 5X, and even that one had a year longer support than your "max 2 years". I'm not saying it's better than an iPhone, I'm saying make a fair comparison.
