Not necessarily. A number of ISPs on this side of the pond are starting to
make a booming business out of selling "filtered internet"; essentially
server-side filtering of web content.

ISPs sell customers whatever it is they choose to sell them. The customer,
as well, has the option of shopping around for the service they're looking
for. If you, as a customer, are violently opposed to your ISP filtering
you, then you have the choices of switching to an ISP that serves your
needs, or getting other customers to try and convince your ISP to change
policy.

Nothing wrong with it at all (my home system, at the end of a dialup link,
does so). Of course, with an ISP that filters outbound port 25 traffic,
you'll want to smarthost everything to the ISP's mail server. Not much
different, in the grand scheme of things.

You've just transferred the burden of dealing with your dialup pool to
other administrators, instead of dealing with the problem locally. Yes,
you may respond quickly to abuse problems, but the fact is that abuse
problems will still occur.

> Doesn't this arrangement make sense?

Absolutely. So does filtering traffic and spam filtering at your central
mail spool to ensure that the problem never happens in the first place.
