Vodafone Finds Brits Keep Mobile Phones for 4 Years Instead of 2

This is a most excellent place for technology news and articles.
It's a little more hands on, but when you reach the end of OS updates support, you can switch to a community-supported OS.
Like Linux? I don't know anything about it. I'd definitely try.
Sorta. (Android is technically Linux) What you would want to look into is a custom Android ROM. Something like OmniROM or ArrowOS.
As a side note though, installing can be a bit technical for some people and some apps don't like to work outside of the "security" of a factory version of Android. If you are interested, I would browse around the custom Android communities here (if there are any yet) and check out sites like https://www.xda-developers.com/
Is that where you have to root it and sideload the OS? I've read about it.
Rooting is a slightly separate thing from sideloading a custom rom, rooting gives apps you give permission to access to system files whereas sideloading a rom replaces the system files but doesn't necessarily give you root access. Both involve a similar process of unlocking the bootloader, installing a custom recovery and flashing a file so it is easy to get the two things mixed up.
Yeah
Also mention lineage OS, Graphene OS and Calyx OS too
No, there are unfortunately no truly workable Linux OSs for phones yet AFAIK. But there are plenty of Android-based OSs that work really well, and are usually maintained for quite a while, depending on the popularity of your device. Look into LineageOS, or Pixel Experience, to name a few.
There's ubuntu touch. I'm not sure how many phones that works on though.
