I mean, no. Their market share says nothing about people’s wants and needs on this topic, it just means that on the whole the Android package is more appealing. Which could be for many reasons, of which price is going to be the biggest.
If people could choose a longer period of updates, I don’t really expect any to refuse.
The fact that Android phone releases (like the one we’re commenting on right now) generally announce the supported feature and security updates indicates that it very much is one already, at least on the Android side.
As long as the apps they use work ok I'm not sure the majority cares about updates security or otherwise.
