I wanted to reply in this direction. Ultimately, literally everything and anything in SW is a sequence of numbers, that anybody could easily put in some kind of table form.
I don’t know where the catch is, but that sentence can not be true in general.
A table of numbers is copyrightable if it represents some creative expression by a human being. For example, a BMP representing a sketch is a table of numbers and clearly copyrightable.
Weights are numbers that come from an optimization process. To the extent that weights encode any creativity, they encode the creativity of the training data. But any company using AI models (including Apple) does not want that interpretation because they are using AI models that were trained on other people's copyrighted works. If weights could be copyrighted, we all of us would own them.
