It isn't the same issue. There isn't a weakness in the lat/lon system
itself (unless you're not using enough digits), but the weakness is in
consumer GPS devices as you say. When using w3w in combination with
GPS, you have to convert it to lat/lon first, so you have to deal with
both the 3x3m inaccuracy AND the inaccuracy of consumer GPS devices.
