Ooh, I know! I'd not exactly call it a moral panic but there were people who were convinced that people would be driving off cliffs or getting lost in the mountains because they didn't have the skills to read a paper map properly. Wasn't very convincing, especially as if people are determined to be stupid enough to drive off a cliff without noticing they're going to find a way to do that even if there's a big sign in front of them saying "Cliff, do not drive off".
In much of the world online mapping services still aren't anywhere near the standard of a proper topological map and there's really no substitute for (say) an Ordnance Survey map if you're climbing in the Cuillins, but that's not the fault of GPS.
Having read a bit about this dispute and the parties involved I think the best settlement prospect for this lawsuit is to set everybody involved on fire.
