It's 700 million monthly active users on the LLaMA 2 release date; so if you reach and exceed a significant number of users in the future, you don't lose your license.
As a purist do I wish it was fully open source? Yes. Is it restrictive to "the rest of us"? No.
Finally, if you have more than 700M MAUs, you probably have an internal LLM you should be using.
It's just "for the rest of us" until we reach a significant number of users and then Meta is gonna come for us.
