Mine is, I have no forward DNS pointing to my machine at all from my bandwidth provider.

You do not have to use the DNS service provided by your ISP, if you do they control you.

You are confusing politics with technology and making a hash of both.

You do not have to use the DNS service provided by your ISP.

Regardless of whether you do or not their ability to filter services is far greater under the port allocation scheme you champion than under a DNS centric model.

If the evil service is on port 666 it is a trivial matter to block it, not so if the evil service is being managed by an independent DNS service provider who maps the SRV record to a port that the ISP has not blocked.

No you need to control your own name. Unless you can do that you are a serf.

That is why it is better to be hallam-baker.com rather than hallam-baker.blogspot.com. Unless you own the DNS name you are permanently at the mercy of the owner of blogspot.com. If their conditions of service change in ways that are unfavorable to you you have no recourse.
