It depends whom I talk to. :-}
(like getting a person in Spain or thousands of miles away)
If I remember correctly, you are visiting Canada now, right? Then you
know that many people there use sympatico mail, which is AT&T. Well, my
ISP is similar, a heavy weight with limited friendliness 
For instance, sympatico users are pushed to use webmail and not a MUA,
the ISP recommends that and does not provide their users with imap
access (only POP3 and they discourage it). Telefonica does give me
imap… I count my blessings.
Other providers (like the one I’m using at the moment with my laptop on
the road) gives IP addresses in the 10...* range, forbid explicitly
P2P and VoIp… Telefonica does nothing of the sort. They don’t have a
very helpful hotline, but at least they do things right.

Me too.
But many people are incapable of that, so I can understand the ISP wants
to do it.

I did that the last time. There was the possibility than a certain
configuration allowed a backdoor for them, but I’m not certain if that
was the cause. It can be that on a certain crash situation the router
simply resets the config.

I don’t think my router has an egress firewall. I can’t check, I’m not
at home.
