It’s all about your intended use. If you want to use Google maps to get to work, the DoD has no problem with web Mercator on the maps backend that serves up your map tiles.

If you’re firing up Arcmap for a GIS project, using the map to navigate based on earth features, or making a reference map, of course the DoD or anyone else, wouldn’t want you to use web mercator

Interesting how Washington, DC used to be within the Southern accent territory, but this has died out to mostly older speakers.

The anecdote that really hits this home for me is that in 2006 they updated the voice on the metro which said “Doors closing, please stand clear of the doors.” The old voice had a southern accent but the new voice did not.
