Meta is not in the AI business. Meta is in the attention business (in this case, actually, no pun intended). If AI is not your product (as in: not how you need to make money), you can be be "generous". Making other peoples products less competitive by aggressively subsidising part of your business is not that cool of a move.
If Meta starts being all open and generous about their core assets, we can start talking. But we will not start talking. Because that will not happen.
