In practice this isn't a matter of how you or I interpret this license - it's a matter of how watertight it is legally. There's no reason to suppose that terms of any commercial licensing agreement would be onerous. At this stage at least these models are all pretty fungible and could be swapped out without much effort, so Meta would be competing with other companies for your business, if they want it. If they don't want your business (e.g. maybe you're a FaceBook competitor), then they have reserved right not to license it to you. In any case, don't argue it with me. In practice this would be your lawyers engaged with Meta and their lawyers, and product licensing team.
