I don't think it's even covering just the last few years but goes back further than that:
> For Chromebooks released before 2021 and already in use, users and IT admins will have the option to extend automatic updates to 10 years from the platform’s release (after they receive their last automatic update).
I don't entirely understand why the 2021 cutoff for it being opt-in vs. opt-out is there. Maybe it's about the "already in use" bit somehow, and making sure that pre-2021 models don't continue being manufactured and sold as as new.
