This is referring to the vast majority of users. At least for a few years
The “vast majority of users” do not know what RAM is and they don’t know what expandable memory means. Nor will they ever open their own laptops. If the laptop is slow after a few years they will just get a new one.
It’s not, at least not on a Mac. It refreshes automatically, I honestly haven’t refreshed my apps in months outside of upgrading to iOS 17.
