Sorry, I was not aware that you were not permitted to criticize anyone unless you invested tens of thousands of hours into building a competing product to demonstrate your point. Something to remember for next time.
You're of course allowed to criticize but, as your "There is no excuse" shows you're not aware of the tradeoffs, especially to security agility centralized platforms do, there isn't too much insight in your categorical dismissal. As someone with tens of thousands of hours of building a secure messaging system, I can say it helps a bit wrt perspective.
