The feature, which was introduced with the iOS 14.1 version last year and connects applications to track personal data with users' consent, hit ad publishers.

 It's been a full year since Apple's new privacy feature, where third-party iOS apps get permission from users to track personal data. As expected, ad publishers have been hit hard. Facebook, which does not hesitate to develop Apple at every opportunity, is the company most affected by the confidentiality agreement. As personal data cannot be tracked, it prevents focused advertisements. Mark Zuckerberg announced that they expect a loss of about 10 billion dollars this year. Analysis shows that this figure can reach up to 12.8 billion dollars. YouTube, another giant platform that generates revenue based on advertising, loses approximately $2.2 billion. Twitter loses $323 million, while Snapchat loses $545 million. These 4 companies have lost 16 billion dollars in total.

 Reports show that iOS users are more vigilant against the tracking feature of apps, thanks to the privacy feature. In this regard, the coming years may be even more devastating. It is thought that Twitter and Snapchat will increase their revenues in the next period as they try to adapt to the new feature quickly.
