Not to mention Google's history of pushing some non-standard behavior into Chrome single handedly to make it the de facto behavior, ignoring voices questioning the motivation, timeline and technical implementation. They are discussed here on HN and everywhere else and easy to find.
Coming back to this, my response is the same: the status quo works, why change it? Similar to how Mozilla responds to replacing user agent with "Hints API" nonsense. I don't want another way to get my location, because I already block all location requests. Google wants site owners to get location more easily out of unsuspecting users. I can't see how this is good for anyone but Google and its friends.
As you assume that GP has not read the post, how about you?
Because google clearly state that the "high denial rates" are a problem, but their framing of the issue is that the users have a "context gap" which needs to be fixed. Because they are convinced that even though users have decided against geolocation sharing with a specific website they want to get prompted about it over and over again as part of the organic interface of the website. And if they un-block it once over the new interface then the previous block will be forgotten and the permission will forever be granted.
A solution respecting their users would be to allow geolocation for duration of the browser tab, but that is clearly not in line with their data collection goals for their advertisers.
Is there any major browser vendor that isn't US based? The only two I can think of are Vivaldi and Opera, which are Chromium based, ergo US tech.
Thinking that everything Google produces might not be positive is NOT jumping into conspiracy theories.
