There are few things quite as emblematic of late stage capitalism than the concept of “planned obsolescence”.
For a school they functionally are. They can’t use them if they can’t get security updates.
and instead the ipad that doesn’t get security updates since 2018 in your example doesn’t count?
Well for starters it wasn’t purchased by or for schools so no. But even if it was, it gets far more than 3 years of support. I think 5 is somewhat reasonable if we’re just going to accept this sort of behavior.
Either way the comparison is not really apt. Mobile devices are far worse about this than PC’s. You should instead compare a macbook (or a cheap windows machine), which gets security updates for 7-10 years. Google knows their devices are very popular for school computers, so to treat them like mobile devices and enforce the terrible standards that comes with is pernicious.
you again chose a macbook for an example, some macs released in 2017 got less than 5 years of OS updates and became ewaste very quickly
choose a different company than apple for your “long time support” examples…
