This is stupid. Google is doing it with their normal process, labeling the USA as a sensitive country in their system and ~~changing the label only for the sensitive snowflakes. So there is no harm to Mexicans in Mexico.~~ (this was wrong, it's show globally in parenthesis, see below)
What sort of damages would she assert anyway? That her country suffers in a significant way from a Google Maps label that can only be seen from the sensitive country? How so?
And if it's a political move what is she hoping to achieve? Google will never cave to the USA before Mexico, they depend more on their US operations than their Mexican ones. So she can't achieve anything politically. Does she want to draw even more attention to a losing fight? A losing fight over mere symbolism no less? Why?
