The pipes themselves must not be regulated based on the content. In other words, freedom for users, not necessarily for ISPs.

What difference between end-users and ISPs means that one party may have freedom but the other may not?

The difference is that we give ISP's the use of our countries spectrum. Without that, they wouldn't have a business. So it's fair that we can prevent them from screwing us through regulation.

If we are talking wireless, then you might have a point, but you can always lay more wire.

True but it's easier said than done. The huge cost involved in laying more wire is a big barrier to entry. And I would guess there are limits to the amount of cable that can be laid.

What difference between government and individuals?

Monopoly on violence.
