I'm sorry, but that is your interpretation of the words, not
what the words mean.

The words are a technical statement: if the root splits, users
might be directed to a different web site than the one originally
intended to have a given URL. There is no judgment in that text,
nothing about "freedom" or seeing "what one does not want to see."
Those are your words, not an implication of the IAB's words.

FYI, the IAB's words originated as a formal comment to ICANN
sent in September 1999 (under my name, as IAB Chair at the time):

The IAB was glad to see that at that time, since it entirely agreed
with the IAB position.

Which particular aspect of CAIDA's view of the Internet do you mean?
There's a vast amount of information there and at other measurement
