It must be a passing thing. Just trendy teenagers hopping on the bandwagon. Another fad from an industry that is addicted to it. It must be these things, despite Github's six years of work on it before release. It must be worth avoiding despite the fact that obvious thought, time, and love has been put into the project.
Yeah, it doesn't do X. It does Y and Z really well, but because it doesn't do X yet it must be eschewed. End of story.
Why would anyone make software in today's day and age that has some sort of business model? For shame, Github, for shame. Github - we know you really grok open source AND have also built an amazing business. But combining the two? Your efforts to create the next generation of text editing is just unthinkable.
Yeah, Atom is just like Sublime Text! Well, except for the core of it being web technology, instantly hackable, and javascript and node being the language for extensions and plugins, rather than python. Oh, and wait until you hear this: Github even ripped off VIM with a plugin called vim-mode!!!
Aghast! You wily Github. How dare you, DARE YOU, try and collect statistical and diagnostic data that will probably be used for improving the product?!!
Hush yourself. Hug yourself. Breathe - it will all be okay.
License looks open source to me - https://github.com/atom/atom/blob/master/LICENSE.md
Even the package file says MIT
Where's the catch?
