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.
You know backdoors mandate this which is why everything is insecure. Most people have no clue that if the government has backdoors then it's always insecure.
When everything is insecure because of backdoors mandated by the goverment then the choosen password does not matter, since the goverment can just access the service/website/encrypted storage without the password.
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?
