SMTP is not entirely blocked. It is restricted to servers on their network.
They have not restricted you from sending mail, they have restricted _how_
you are allowed to send it.

So you don't like their management of their network. It's no different from
any office policies made by system administrators every day. You work at an
office, and the network is setup to restrict SMTP access through the
company's SMTP server. That's a perfectly sane and acceptable policy.
Just because ISPs provide internet access to a much large user base than any
one company doesn't mean they are not entitled to make a decision such as
this one. It's their right. It's their business and their network. They
can do whatever they want with it. If you don't like it, find another ISP.

Maybe they will someday realize this policy is not very smart. But they are
totally allowed to pretend they are being clever. Even if they are not.
