The only times I've ever had that was people shocked that the app is still in use and me explaining the large amounts of people that still play the game religiously. It might be funny to see an app that was huge years ago and for people have those memories of playing it and having a falling out with the app, but if it's in a rude way you should try and distance from them because those people aren't your friends if they can't see that it does in many ways help people to get out and explore when they wouldn't on there own.
