One way to look at it though is how easily many consumers are migrating to Chromebooks from Windows PCs (Chromebooks sales have increased over 600% during the pandemic). Since so much can be done in a web browser now, the migration isn't too hard for a considerable number of users. I think the strongest point on your list is the security migration. Hardened Linux has become a preferred OS for militaries and intelligence agencies, but there certainly is a great deal of training and certification involved with setting up SELinux, AppArmor, etc.
