It's a safe bet that these services are still keeping track of this information for their own advertising and marketing purposes. It's also worth keeping in mind that even though some social media services like Facebook do remove location data before the photos you upload are posted, this just prevents other users from seeing where your photos were taken. Even with Facebook, which is famous for tracking you all over the internet, you may not be comfortable posting an image that carries so much precious data. When you’re posting photos to social media, especially on Twitter, you probably don’t want to post a photo that’s too close to home - or in your home - without a way to remove that information and protect your privacy. When you share a photo with geolocation coordinates tagged in a photo’s EXIF data, viewers can use their own Photos app - or any number of third-party apps - to figure out where the shot was taken. Most of the time, photo location metadata is welcome - but sometimes it’s not. It assists in sorting out photo shoots and helps keep track of family and friends over the years.

This is an enormous convenience, as it allows you to catalog your many images according to exact location as well as occasion. When you snap a photo on your iPhone or iPad, the iOS Camera app automatically uses GPS to record the exact location where the shot was taken.
