It's pseudoscientific to compare the information from a virtual intranet with one from the internet.
It is fine, if the reader also has the context as you offer below.
By "intranet" I mean the limited internet on the other side of the Great Firewall in China.
Intranet generally means more of a LAN than a WAN. I'd go for a different term.
The meaing of "virtual" not obvious here.
It's pseudoscience to compare the information from a virtual intranet, formed by isolation frrom the internet with a firewall, with one from the internet.
.
BTW: I disaggree. What makes it pseudoscience or not, is the quality of the comparison that you do.
An isolated LAN is smaller than the internet. - A non-pseudoscience comparison.
It is pseudoscience to take results from a <description you want> and assume that they apply to the internet in general.
