Few people outside of the tech nerd bubble care about this.
What they do want is an inexpensive phone that still runs the latest software. Because Apple models are supported so long, people can buy used, old iPhones that still run the latest software.
Others trade in their phones often because they always want the new shiny. Because Apple models are supported so long, the used phone they trade in has more value, allowing them to fork over less cash for the latest Pro phone.
These are the sort of factors that drive Apple’s market share up.
You (usually) can run the latest software on an old Android nowadays - the reason is that many of the functions which were previously baked into the system are now part of Google Play Services, which are upgraded like any other software package.
The only app to tell me that it will stop updating on my 5-year-old Android phone was... Slack.
I personally couldn't care less about this. I just want a phone that works well for me.
If it were just security updates, I wouldn't mind automatic installations. But feature updates are too disruptive. So I avoid automatic updates where I possibly can.
I accept that there's a security risk associated with doing this, but for me, it's a risk that's worth taking.
Security updates are not optional.
I'm considering an iPhone for my next phone, although I'm a Google Voice user which makes me a little nervous about that prospect, plus I've been less than impressed with Safari's extension ecosystem.
If you read the OP linked report, contrary to the popular sentiment here and on Apple sites, that more people hold on to their Android phones longer than iPhones despite the lack of security updates
What is the point in "security updates" for a CPU that can't be made secure?

From a support after the sale perspective? Yes it is.
The $399 2016 iPhone SE is still getting security updates today.
The original Google Pixel is also from 2016 but stopped getting any sort of updates at the end of 2019.
If you want a basic phone that will be supported as long as possible after the sale, the support length per dollar spent proposition of the SE models is pretty unbeatable.
I think this is a major factor that is driving market share towards iPhone.
