That's simply not true. The reason why llama is open source is simply because it got leaked, then llama.cpp was the real game changer which was built from the ground up in depressingly short amount of time. Meta had no choice but to take the L and "support" the open source community. The angry "I-hate-you-and-I-hope-you-die" kind of support.

It arguably didn't really get leaked, and they had the .edu req mainly for fair use education exemption when legality of models was much more uncertain.

Why do you think they continued to do it?

Ps: I work for meta, but not in AI related orgs.
