People view weights as an intended obfuscation by the party releasing it. It is not! In fact, it is equally as hard for them to "understand" why a certain value at a certain index is what it is, as it is for you! Just ask Anthropic. They are also doing poke this weight, see what pops with their own models.
Again, that is why I used the analogy above. You are arguing that if someone uses a hardcoded value in their code, and won't share how they derived that value, it somehow isn't open source. That, IMO, is wrong.
