My main browser, Firefox, has uBlock and Self-Destructing Cookies. Tried it in both IE11 and Edge (both of which I never use), and I got pretty much the same result. Firefox and Epiphany on Gentoo Linux also failed to startle me.
I'd like to see a screenshot of a "worst case scenario".
Are you saying it showed your geo location without having prompted for it, and that you're OK with that?
