Engadget reports, that with iOS 13 Apple started checking website details against fraudulent behavior with Tencent. While Apple already uses “Google Safe Browsing” to improve security, this behavior has been difficult before. With the latest developments in Hong Kong and China, this approach is – at a minimum – questionable and overshadows trustworthiness of Apple hardware. Engadget comments accordingly:
You might not have to worry outside of China, but it’s still a concern.
