As part of iOS 14.5, Apples App Tracking Transparency forces developers to ask permission for something they used to be able to do for free: track iOS users. Today, Twitter is joining the ranks of other developers and adding a prompt that asks users to enable tracking on iOS (via MacRumors).
Twitters main justification for listening to its request is straightforward having the feature enabled allows it to serve better ads. The company includes a link to settings so you can make those changes, but read Twitters explanation before you decide:
Keep ads relevant to you by allowing Twitter to track data from other companies on this device, like apps you use and websites you visit.
Its a surprisingly low-key attempt to get users to allow Twitter to track them, considering the company highlighted Apples addition of App Tracking Transparency in iOS 14.5 as a potential risk in its recent earnings statement (PDF):
We continue to expect total revenue to grow faster than expenses in 2021, assuming the global pandemic continues to improve and that we see modest impact from the rollout of changes associated with iOS 14.5. How much faster will depend on various factors, including our execution on our direct response roadmap and macroeconomic factors.
Facebook and Instagram took a far more aggressive approach to convince users its use of ad tracking is on the up-and-up even going as far as including a vague threat that enabling tracking will help keep Facebook/Instagram free of charge.
Companies like Twitter and Facebook rely on tracking users to support their separate, often very lucrative ad businesses. After all, its usually ad sales that pay for free social networks, and customer data helps to target those ads. As a company thats more interested in selling hardware and subscription services, Apple doesnt really have to worry about things like that, but brash changes like the new tracking permissions can leave developers scrambling.
App Tracking Transparency has proven popular, though around 96 percent of US users are opting out of tracking according to some recent surveys. And with Google considering developing its own methods for blocking tracking on Android, we might just have to get used to apps coming to us and begging for free data.
