It basically crashed my computer. That is “hard”. Somehow my computer picked up something called “Stuffit” and it was super annoying.
Unpacking a file crashed your computer, and installed a program which won’t run on Linux? That is certainly interesting. But, I don’t really see how it demonstrates that unpacking itself is hard. It might show you did something you shouldn’t have, or were trying to open something which shouldn’t have been opened. These are equally possible with any OS and so it doesn’t show that a particular task is hard to do. Double clicking is simply not hard, and since that is how the same thing is done in Windows it just doesn’t seem possible to argue that it is harder in Linux.
