I don't disagree but I think it's not a question of "why" but "how". It could still be licensed in a restricted way, but keeping secret how it works is unfortunate - it breaks the chain of learning that is happening across the open ecosystem and, if the technique is any good, all it does is force open models to build an actually open equivalent so that further progress can be made (and if it's not really any good then it's snake oil, which is worse). Even if it's great it essentially becomes a dead end for the people who actually need and want an open model ecosystem.
