I think the license choice is great. It allows noncommercial use, modification, and redistribution. It’s not “open source” according to the champions of the term (since it violates the use-for-any-purpose requirement) but I’m a huge fan of this license and license several of my projects CC-NC-BY where AGPL would be too heavy-handed.
"It's not recognized as Open Source by the Open Source body, and doesn't meet the criteria of Free/Open Source Software, but is Open Source" is a bit like saying "I used GMO and petroleum based pesticides, but my produce is all organic."
Why should words like "organic" in relation to food mean without pesticides? I mean all carbon and water based life forms are organic, right?
I can define Open Source easily, using the OSI definition.
There is not a trademark for Open Source because they failed to secure the trademark, but we have decades of use for the term meaning something specific.
