Could you expand on that comment. Do they include attribution to the authors (as they have in blenders license) and all notices that refer to the license?
In general, in order to be in compliance they also need to:
You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
And either accompany source code along with executable, or a written offer for source code.
Including a copy of the GPL is a nice first step. Do they follow the remaining conditions?

I don't know.
I'm not entirely sure which libraries licenses are alleged to have been infringed upon. The string "blen" doesn't appear in the Licenses.docx file. There are another ~10 license text files in that folder for libraries that might be Blender-flavored.

Again, I can't say, I'm not sure how to search for it without getting false positives and I'm not committed enough to read through that much licensing text.
I agree with my sibling commenter on his assertion that including the license (that mandates furnishing source code on request) is itself an offer to furnish source code on request, but I understand where you're coming from if you don't.
Interesting side note, in the Licenses.docx file there's also a copy of the GNU Affero GPL3 license. I've no idea what they've included that uses that license, but I think the possibility that they've included AGPL3 licensed code could be much messier.
Yep. It's in the install directory under /Licenses/Licenses.docx, Appendix B, provided with the Program as required.
