“Early on 20th May, KryptoKit users started reporting that the extension was mysteriously removing itself from Chrome without prior notice. They also found that the extension had disappeared from the Chrome app store. KryptoKit project developers tried their best to work out a solution, but it soon became apparent that Google itself was behind the abrupt removal. Google reinstated KryptoKit’s account a few hours after the issue was detected, but, it did not offer an explanation at the time. Finally, Google’s Chrome team took to reddit last night to explain what happened, with Google Chrome Product Manager Tyler Odean apologizing for the confusion and explaining what caused the problem.”
