True and you may well be right. My experience may not reflect the norm
either.

I've long agreed with you and even argued this way in IETF groups. I've
come to change my mind and see that the DMARC setting helped them fight
abuse taking place at that very moment, at a relatively minor cost (very
few people use mailing lists).

I've also come to see that the way mailing lists work, though completely
valid according to all standards, makes it impossible for domain owners
to protect the occurrence of their domain in the From field. This is bad
for security and goes against how many people expect email to work.

It is not uncommon for new security measures, often unilaterally decided
by the Google's and Microsoft's of this world (almost always the former,
actually), to prevent people from using things that have worked fine for
years. Think of a stricter SSL/TLS requirements that prevent you from
accessing an internal server, even though the threats the measures
protect against aren't relevant at all.

It's always sad when it happens, but often these things are in the
common interest.

I don't think Google, Yahoo, Microsoft and many other local webmail
providers would agree with that. Email is relatively cheap to run
anyway. These companies also tend to run hosted email solutions, which
are quite popular and likely make them quite a bit of money. Probably so
much that it might be worth running the free webmail service purely for
the extra telemetry (which can be used to improve spam filters etc) it
gives.

Also, if Yahoo and AOL would have wanted to let email die, they wouldn't
care very much about spam. The strict DMARC setting, whether you agree
with it or not, was an active way to fight that.

I actually meant unencrypted data in general, whether it's SMTP, HTTP or
something else.

Yes, email has some fundamental issues when it comes to security in
general and encryption in particular. I hope we can slowly replace it
with something better.
