The question is what is "open source" in the case of a matrix of numbers, as opposed to code. Also, are there any "IP" rights attached at all to a bunch numbers coming out of a formula that someone else calculated for you? (edit: after all, a "model" is just a matrix of numbers coming out of running a training algorithm that is not owned by Meta over training data that is not owned by Meta.) Meta imposes a notification duty AND a request for another license (no mention of the details of these) for applications of their model with a large number of users. This is against the spirit of open source. (In practical terms it is not a show stopper since you can easily switch models, although they all have subtlely different behaviours and quality levels.)
