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.
Pixel 6 came out last year, the 5 year promise is still just a promise.
Samsung's 4 years isn't 4 years of major Android version updates. IIRC it was 2 years of Android updates + 2 years of security patches.
We'll see in 6 years whether the Nexus 6 can get the latest Android version. I'm pretty damn sure my iPhone 14 will still get updates in 2028.
A lot of people buy cheap $no-brand phones that probably don’t get (any) updates.
