And I'm not arguing that they should release open source models. There's no shame in releasing an open-inference model. But I think I'm fair in saying they should use an accurate term for what they do release.

There is nothing "source" about the "open source models" that companies typically release. The use of the term "open source" is deliberate marketing BS. If you want to argue there's a difference between software and a model, then don't use software terms that are already well-defined to refer to some property of the model.
