Just noticed these types of copyright/license headers in the atom-shell source code
// Copyright (c) 2013 GitHub, Inc. All rights reserved. // Use of this source code is governed by the MIT license that can be // found in the LICENSE file.
I’m not a lawyer (or similar), but I’m pretty sure there are conflicts here. You cannot both use the MIT license, yet reserve all rights. The whole point of an open source license is that very few (if any) rights are reserved. I’m pretty sure the “All rights reserved.” part needs to be removed to avoid conflicting terms. The clue to this is to actually read the MIT license, which specifically states that anyone obtaining a copy of the software has rights to redistribute, modify and what not, as long as the copyright notice (e.g. the LICENSE file) is redistributed as well.
