TIL that a chromebook I bought a couple of years ago (intending to install Debian on, but got shelved until an immediate need for kids in online learning) has been officially abandoned for security updates by Google. I didn't realize how short the interval was before Google forced a choice between using an insecure browser or creating a massive amount of ewaste.
Luckily I should still be able to liberate this one (thanks Debian!) but most people won't. What a sad state of affairs.
