Apple ruffled a few feathers in the tech space with the addition of a new Do Not Track feature - Facebook and Instagram are now taking things on the offensive.

With iOS 14.5, you can ask apps to not track you across services and different apps. Tracking is just a creepy thing to do. This is how services like Facebook and Instagram survive unfortunately, offering users targeted ads while snooping through the path you walk through social media. That last part means you are essentially giving up on your privacy completely, something which a lot of people aren't so keen on giving up.
