As soon as Canonical blows something off in Ubuntu, users can switch to whatever other Linux distribution they like (or remove/replace the misbehaving component, like it happened with the Amazon thing or early-ish versions of Unity). Apple users can't very easily switch to a better version of macOS (especially when they need to migrate their data out of the walled garden it's hosted in).
