FWIW the only two apps that my S20 came with that I wish were uninstallable are the Tips app and the Samsung calendar app, and there is a good reason for the latter (if a user managed to delete all calendar apps on Android the OS does not like that at all). They're pretty trivial to hide.

But some people might have to accept the presence of a Facebook shim for installation is such an incredibly mainstream proposition that they are in a vanishingly small minority wanting rid of it.
