Computers were able to work without internet since i was a kid. That's how me and my friends used them without any problem. Using the airgap word you are making it a new special setup that needs some special steps, some programs will not work etc. It's not a feature.

Saying people prefer one to another hides the fact that they were not given any other option. People will choose whatever default is given and then we may say they everyone prefers that. Or just make the other option (which was normal before) complicated so that nobody wants that now.
