The intranet is a work network for doing work on. You can still look up infowars on the internet, as long as you're not doing it during work hours.

The intranet is designed for accessing military information systems mostly for work projects, personnel management, personal records, and emails.

This is as much censorship as trying to use the intranet to go to pornhub.

Speaking from experience, a lot of sites are blocked behind Military firewalls for 'information protection'.
