I feel like those restrictions don't violate the OSD (or the FSF's Free Software Definition, or Debian's); there are similar restrictions in the GPLv2, the GPLv3, the 4-clause BSD license, and so on. They just don't have user or revenue thresholds. The GPLv2, for example, says:
> c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)
And the 4-clause BSD license says:
> 3. All advertising materials mentioning features or use of this software must display the following acknowledgement: This product includes software developed by the organization.
Both of these licenses are not just non-controversially open-source licenses; they're such central open-source licenses that IIRC much of the debate on the adoption of the OSD was centered on ensuring that they, or the more difficult Artistic license, were not excluded.
It's sort of nonsense to talk about neural networks being "open source" or "not open source", because there isn't source code that they could be built from. The nearest equivalent would be the training materials and training procedure, which isn't provided, but running that is not very similar to recompilation: it costs millions of dollars and doesn't produce the same results every time.
But that's not a question about the license.
It may not violate the OSD, but I would still argue that this license is a Bad Idea. Not because what they're trying to do is inherently bad in any way, but simply because it's yet another new, unknown, not-fully-understood license to deal with. The fact that we're having this conversation illustrating that very fact.
My personal feeling is that almost every project (I'll hedge a little because life is complicated) should prefer an OSI certified license and NOT make up their own license (even if that new license is "just" a modification of an existing license). License proliferation[1] is generally considered a Bad Thing for good reason.
