> And really, it just boils down to a shitty planned-obsolescence business decision. Apple knows that they will have enough people to buy (either first-time or upgrade) their newest shiny iPhone come release time every year, even if they continue to support 8-year old phones. Google doesn't have that confidence, so they don't put as much effort into upgrades for older devices. And that's Google, who makes fairly high-end phones; the makers of low-end devices know their users are price-sensitive and won't upgrade phones unless they have to.

I'm not convinced. Apple controls the iPhone market and can do this, but no Android manufacturer controls the Android market. A brand that deliberately reduces its own devices' lifespan can't trust that its consumers will buy another device from the same brand. I think it's just a matter of not offering support being cheaper than some plan to reduced lifespan leading to new purchases.
