There's a still a big catch: normally, when a computer "runs Linux", you can keep installing new Linux distros until the hardware dies, which could be decades in the future.
You can install Linux on some Chromebooks, but it's often a lot of work to disable the "press Space to erase your operating system" prompt. It would be better if all EoL Chromebooks received an update to disable secure boot, because secure boot stops being secure when it boots you to an unpatchable OS.
Chromebooks reach "end of life" after a few (edit: ≤ 6.5) years, effectively becoming software-defined garbage: https://support.google.com/chrome/a/answer/6220366
