It looks so, but the wording is wierd (to my untrained eye): ``` Permission to use, copy, modify, and distribute this software for any purpose without fee is hereby granted, ... ``` the fact is that "without fee" comes before "is hereby granted", not after, so that it looks as a condition to the distribution grant. Indeed the canonical MIT license does not mention fees and the "free of charges" is clearly referred to the permission: https://opensource.org/licenses/MIT > You can ignore this file and consider u9fs is distributed under MIT. Thanks! But I think that to avoid future issues, the Plan 9 Foundation should either remove the file or complement it with an explicit statement about the new MIT licensing.
