I don't have eyes inside of Meta, but keep in mind that we're not just talking about fine-tunes and LoRAs, we're also talking about the entire llama ecosystem, including llama.cpp, ollama, and llamafile. These would not exist (or wouldn't have anything like as much momentum) without Meta's investment, but they're now huge community projects. I don't know if they use them internally, of course, but they could, and they represent a lot of work.
