That reminded me that almost 10 years ago ghacks [1] instructed people to add _nomap to their Wifi networks name to avoid these being harvested by Google and Mozilla. I wonder if that ever worked or still does and if companies stopped collecting that information.

Officially this is still supported. With that said, there have in past years been data sanitizing failures which get them mapped anyway. Google caught a little flack for that several years ago.
