Thanks for a nice, cogent analysis. You did miss one sub-case, though,
which may generally be a minor issue.

The subcase is:

  2. (b) Privacy/paranoia -- they're doing something _legitimate_ that
     they don't want visible to their provider.

Before I got a static IP at work, I needed to use my employer's server
to send mail. My employer had a stated policy reserving the right to
intercept and read mail sent through the company server. They had no
policy forbidding the use of SMTP without their server, and they had
no policy against personal email on company time.

Hence, to protect my privacy, I chose to send personal mail from my
own Linux laptop, circumventing their server.

Yes, I know--that's security through obscurity. I also used PGP, when
applicable. However, it was a matter of principle with me to at least
circumvent their stated intention to violate my privacy at will.

Hence, this is also a subtype of:

It is your right, if you are an ISP. It will make many of us Linux
users sad, because you have forbidden our "playing". It's rather a
pity, in my opinion.
