So what?  Someone showed up here and said it is actually all about
security.

That is obviously false to anyone skilled in the field.  You don't
build better security by building another gigantic layer.  That
is obvious to anyone who actually works in the field.

The people who are being fooled are just being 'users'.  They need it,
so they invent all sorts of judgements to make it OK.
