[License-discuss] Does the LinShare "attribution" notice violate OSD?

[Josh Berkus]

Folks,

Someone just forwarded me this:

https://github.com/linagora/linshare/blob/master/COPYING.md

Take a look at "additional terms", esp:

> In accordance with Section 7 and subsection (b) of the GNU Affero General Public License version 3, these Appropriate Legal Notices consist in the interface display of the "LinShare™" trademark/logo, the interface display of the "Libre & Free" mention, and the interface display of the "You are using the Free and Open Source version of LinShare™, powered by Linagora © 2009--2020. Contribute to Linshare R&D by subscribing to an Enterprise offer!". The latter notice must also be displayed in any asynchronous message sent with the Program, for example e-mails which will contain this notice in their footer. Retaining these Appropriate Legal Notices in any and all Free and Open Source versions of LinShare and LinShare software Programs is mandatory notwhistanding any other terms and conditions.

... this is the most burdensome example of an attribution notice I've 
ever seen.  Feels like it's a violation of 10, and possibly 6 or 8 as 
well. Thoughts?
