“They are still mostly denying the existence of the internet - except that preflight briefing is de facto now impossible without it.”
No, that is not the case. It is possible to phone up and get a weather brief (at a cost). It is possible to phone up and get Notams. It is possible to work a plog out without the Internet. You can still fly without ownership or access to a computer. I would not wish to do it, but I know people who do.
