Does a rat who has lived its entire life in a cage realize it is in a cage?

Just because they haven't actually experienced the internet and have been
fooled into believing what they have is access to the internet does not
make the claim any more accurate.

As I said, they don't have internet access. They have a controlled
and limited subset of the features that define internet access.

The internet is a peer-to-peer network where each system has a
globally unique potentially reachable address and can operate
as both client and server. Machines behind a NAT have access
to only a subset of those defining features.
