Doubt this is possible because so, so many people use EOL phones, but still.
Because many people have fortunately realised that "EOL" is just an excuse to create lots of e-waste and push even more hostile unwanted changes.
Eh, not really. Using EOL devices is genuinely a bad idea, it's just that with phones you have no choice due to the updates usually being only like 2-3 years and alternative OSes not being as accessible as Linux. And most people don't even care or know anyway.
I would attribute EOL phone use to largely to being frugal or poor. I'm sure at least one person considers the ecological factor but I'd expect that to be a small cohort.
