Facebook and Zuckerberg don't like this new upgrade.

But you and me get more privacy and some other benefits.

Benefits: "Other iOS 14.5 updates include being able to unlock your iPhone quicker while wearing your face mask, and change your Siri’s go-to music app to your chosen music platform. Users will also get more diverse voice options for Siri—amongst other new things."

Privacy: "With the latest iOS 14.5 update, Apple introduces their new App Tracking Transparency (ATT) feature" which "provides users control on what apps are allowed to track for personalised services, data sharing and targeted advertising."

Controversy: Facebook say the small businesses will suffer because they can't advertise as easy than before. Of course, Facebook can't earn money as easy than before too!
