It’s far worse, just last week I was assessing some architecture and there’s still dial up and 3G connected devices in some of the most critical infrastructure around..
Used to drive me mad that the clipper terminals in the SF Caltrain station used dial up, in 2017!
I don't see the issue with either of those things? At least as long as they're properly secured. (Which they probably aren't but that's neither here nor there.)
