I don't use atom, but I don't understand why it needs to be defended or why people would attack it in the first place. If you don't like atom, like me, then don't use it. Is it deep down that you are really envying people using atom as their daily driver while you can't (do the same comfortably)?
After all, it is just a text editor, not like a hot technology that your boss will force down your throat, right?
