What you said applies more to you than it does to me.
You don't even have that. From what I can tell, you have literally no argument at all; instead, you "agree" with the article while drawing exactly the opposite conclusion that the article draws, then point out again and again how much users don't want to install things, as if that changed the security of this system at all.
Scramble performed encryption on the server, then my argument is false. But the design of Scramble's protocol is such that the security of the application depends only on securing the client code, which I argue can be done, for those who set up their environment correctly.
