Changing the rules is definitely more work than maintaining status quo. Imagine a giant bureaucracy and all the things that are would need to adjust. And granting prisoners even limited internet access is fraught.

A close friend of mine taught physics and programming in San Quentin and for the most part his students couldn't use even a restricted variant of the internet. He told me guards would complain that he was "making criminals smarter".

He ended up hosting a local copy of Wikipedia for student use, but to make the prison staff happy he had to remove any controversial articles from it, like "lockpicking" and any article with explicit imagery.
