It sounds unconstitutional because it is. The government should not be able to buy geolocation data gathered by the apps on your phone without a warrant. https://www.nytimes.com/2021/01/22/us/politics/dia-surveillance-data.html

@eff What's most disturbing, #EFF, is that we simply expect the gov to stop buying commercially available data, as if that would end privacy abuse.. as if corporations don't abuse it themselves. The real fix here is for the ppl to stop feeding the data brokers.

@resist1984 @eff For a start, DoH and VPN usage can reduce the amount of data available for ISPs to mine.

@rporter @eff that's a good start, as long as #CloudFlare is not the VPN provider & out of the DoH loop. OTOH, the VPN just moves the risk to the VPN svc, so #Orbot/Tor is better. But in the context of the OP, neither will help if the app xmits your IMEI w/gps coords.

@resist1984 @eff For the average user, total privacy is impractical. My focus with my clients is to help them avoid accidentally giving data to the major players, such as Google or Facebook.
