Hopefully I'm not violating copyright by taking this small chunk of their LICENSE.txt, but this appears to be the language that some want clarified:
https://github.com/mattermost/mattermost/blob/master/LICENSE...
----
You are licensed to use compiled versions of the Mattermost platform produced by Mattermost, Inc. under an MIT LICENSE
- See MIT-COMPILED-LICENSE.md included in compiled versions for details
You may be licensed to use source code to create compiled versions not produced by Mattermost, Inc. in one of two ways:
1. Under the Free Software Foundation’s GNU AGPL v3.0, subject to the exceptions outlined in this policy; or
2. Under a commercial license available from Mattermost, Inc. by contacting commercial@mattermost.com
"Subject to the exceptions" conflicts with the "no exceptions" wording in the GPL licenses, so I don't even see how any of this constitutes a valid license
AGPL does not say "no exceptions". AGPL explicity allows exceptions:
https://github.com/mattermost/mattermost/blob/master/LICENSE...
https://www.gnu.org/licenses/agpl-3.0.en.html
I read the exceptions as a grant of additional rights to mattermost's copyright (but not to third parties), I don't think that conflicts.
I'm not sure that they actually granted a GPL license at all though. I could see this document being read as an advertisement that one might be for sale instead of a grant...
