You're seeing this as a technical issue when it is in fact a legal one. In Canada the telecommunications legislation states the principle well:

(2) No Canadian carrier shall, in relation to the provision of a telecommunications service or the charging of a rate for it, unjustly discriminate or give an undue or unreasonable preference toward any person, including itself, or subject any person to an undue or unreasonable disadvantage.

You can still manage networks and employ CDN. But you can't arbitrarily block content.
