YMMV, but I do not need to carry a significant proportion of global
emails. In fact, all those listed above and plenty others are
permanently blocked on my mail server for over a decade plus because of
their "free speech" stupidty of passing on what is clearly spam.

SMTP wiill be a very long time dying when the names' business models
are all about exploiting their marks/customers.
