I have a google nexus 7 tablet from 2013. Thanks to Google unlocking all their bootloaders by default, I can install u-boot and a modern linux kernel on it (thanks PostmarketOS).

Since linux runs on it, I can run the latest versions of great pieces of software like ed, slack in a web browser, etc.

It is 100% apple's fault that they do not open up the bootloader for devices they'll no longer offer updates for and allow the community to build a custom darwin or linux fork. Even though we paid for the hardware, we are not allowed to use it any longer than apple says.
