This isn’t to say that all free, ad-financed apps are bad and all pay-to-play apps are good. I’ve used Foursquare and Swarm consistently for 7+ years. These are apps where I volunteer my location, travel, eating, and shopping habits, and I’ve never had the slightest sense that Foursquare was using this data in a way that made my life worse.
Do you really believe that you are holier, in more favor, and loved more by God? When Jesus said not to judge other people, or to the same measure that you judge them, you will also be judged — did that sink in?
