I don't really get what the objection is here, if you're using maps with GPS, Google has your location, adding precision to that helps you more than it helps them, they don't need sub-metre precision to know what store you were in, but your navigation prompts to switch lanes in a more timely manner becomes possible/more accurate with this, especially in cities where buildings mess with satellite signals.

This seems like hating Google because it's Google, not because this particular action merits any hate at all
