Obviously it's hard to predict the opinions of the dead, and I think a lot of the disagreement here comes from whether they view his ideas as being motivated by anti-copyright as a standalone idea or part of a larger pro-little-guy stance. I think depending on which you think it was, you can come to a different idea of what his view would be on open models. But surely both views would lead to an anti-closed models stance? Would a hypothetical generation later Aaron want to publish the weights for Claude rather than academic publisher articles?
