ZDNet:

Apple said this week that it declined to implement 16 new web technologies (Web APIs) in Safari because they posed a threat to user privacy by opening new avenues for user fingerprinting.

The vast majority of these APIs are only implemented in Chromium-based browsers, and very few on Mozilla’s platform.

Apple claims that the 16 Web APIs above would allow online advertisers and data analytics firms to create scripts that fingerprint users and their devices.

Take a look at the list of APIs being blocked. As Jan Wildeboer said on Twitter, “The browser is becoming a backdoor, almost malware with all these possibilities.”
