>will give the next generation of smartphones 30-centimeter accuracy instead of today’s 5-meters Didn't the US scramble the civilian signals specifically so it wouldn't be too accurate? And they're just okay with civilians having access to ultra accurate GPS receivers?

Civilian GPS signals used to have intentional error added, but that was ended in 2000:

I may just be a super-cynical ad-tech exile, but I see this as a path to getting shown more ridiculously well-targeted ads based on the places and stores I've been in. Beacons haven't taken off and I'm glad they haven't. I'd really prefer a GPS in my phone with a similar granularity to the one I have now. Google's notifications that I should review places I've been are creepy enough.

It's almost as though using a phone whose operating system is created and maintained by an advertising company isn't the best idea if you want to keep things like your location private.

For what it's worth, all operators have a legal obligation to gather these data (at least in the U.S. and Canada) officially for emergency services purposes.

The toggle for that notification is in the Maps app under Hamburger > Settings > Notifications > Your Contributions. (If you think that's buried, you should see the developer menu.)

The difference between 5m accuracy and 30cm accuracy isn't terribly important if you're just trying to tell what building someone is in, and it won't improve in-building accuracy. I can't think of anything sketchy that it enables that someone couldn't do already.

All the more reason for people to switch from Android to Apple ecosystem.

Earlier quoted context omitted.

But that's client side right? What's preventing someone from implementing a GPS receiver using a SDR that doesn't have those restrictions?

Nothing at all: http://www.aholme.co.uk/GPS/Main.htm

Boy do I miss those types of sites. I need to find more of them.

Apple has location-based ad targeting on by default, too.

Apple is also an advertising company - they have unique IDs with your personal information pinned to them, and they sell ads based on your location, too.

You can change your advertising ID any time you want -- and almost none of their revenue comes from ad sales. In 2016, $190B of their $215B in sales was definitively not from ad sales, and the $25B services category that would include ad sales also includes the percentage of sales from the App Store, Apple Pay, Apple Care, iCloud.. etc. Ad sales are immaterial to their business model.
