The alternative is older versions of Android, from before these hostile changes. The propaganda that it's "unsafe" is just that, propaganda. Perhaps Google will realise once enough of the population refuses to put on the noose.
It's totally unfeasable for those using stock deviced. Refusing to upgrade takes lots of attention even from experienced users like developers. Regular user just doesn't have any chance to avoid accidentally clicking or intentionally accepting the annoying permanent notification to upgrade OS.
The problem is not the propaganda, it is the businesses restricting the freedom and choices of users because of this propaganda.
So many apps even refuse to be installed on older versions of iOS/Android.
The bank app, mandatory updated to the latest version, does not run on old android.
the majority of the population will happily put on the noose and they will join in on pressuring you to do it too. Don't kid yourself. However, a successful resistance movement only requires like 3% of the population or something
