MIT License can't have "all rights reserved." #2129
Description
According to README.md, PowerShell is licensed under the MIT License. However, when I open LICENSE.txt I see the following:
PowerShell 6.0
Copyright (c) Microsoft Corporation
All rights reserved.
MIT License
Permission is hereby granted, free of charge, to . . .
How can all rights be reserved while granting all the rights under the MIT License? To reserve all rights while granting all the rights under the MIT license is completely contradictory. Of course, Microsoft can retain the copyright but it can't reserve all rights and license under MIT.
