Then it is unfortunate that the general behavior of (some big?) app developers has made it so necessary to eschew updates by default to avoid change-for-the-sake-of-change workflow breakages (e.g. how Mozilla went about rolling out Fenix) and to dodge the threat of user hostile changes (e.g. the ad and tracking nonsense we see so often on Windows updates). This is a problem of their own creation, trying to tell users to accept it anyways is a non-starter for many.
