Which clause are you calling "you can use this at our pleasure"? The license is short and there is no such thing. The most restrictive item is whether you had 750M active users in the month before it was released. [1]

The availability of these weights and code are propping up an open source community around LLMs, which lends oxygen to other even-more-open endeavors.
