For personal or noncommercial use I agree the restrictions are meaningless. As they are for "bad actors" that would potentially abuse the tools in contravention of the license. But the license terms are a risk for commercial users especially when dealing with a big company like Meta. These risks werent previously there in say pytorch that is MIT licensed. The ironic thing with these licenses is that they are least enforceable on those who would be most likely to abuse them: https://katedowninglaw.com/2023/07/13/ai-licensing-cant-bala...

Re success of free licenses, linux (other than a few arguable abuses) has remained free and unencumbered thanks to GPL licensing.
