I didn’t read the article, but Apple does advertise a certain level of privacy and security with iMessage. A company getting around that kind of defeats apples “promise”.
So, I don’t blame them for turning it off, but they realistically should bring iMessage to android.
Advertising privacy does fuck all when Apple has been allowing the government to read push notifications. Where does that promise fit in, while they knowingly supply what the government wants and then still market itself as a privacy friendly company?
