For those unfamiliar, Twitter has a geotagging feature that will allow users to precisely tag where they are at. It is a completely optional feature and those who don’t use it won’t have their location shown, but it is (or rather, it was) there should users ever decide to take advantage of it. However, according to Twitter, it seems that the majority of Twitter users do not use it, so much so that they have decided to take it down.
This seems to be less about protecting privacy and more about saving resources that could be used for other projects. According to Twitter, “Most people don’t tag their precise location in Tweets, so we’re removing this ability to simplify your Tweeting experience. You’ll still be able to tag your precise location in Tweets through our updated camera. It’s helpful when sharing on-the-ground moments.”

That being said, there is no mention if this will mean that older tweets will have their precise locations removed, or if this will only apply to new tweets moving forwards.
