This, in my view it's a (very smart) move in response to OpenAI/Microsoft and Google having their cold war-esque standoff.
Following the analogy : Meta is arming the Open source community with okish (but in comparison to the soviets and Americans shoddy) weapons and push the third position politically.
Amazon meanwhile is basically a neutral arms manufacturer with AWS, and Nvidia owns the patent on "the projectile"
I'm not trying to biting the hand that arms me - so thank you very much Meta and Mister Zuckerberg.
Now someone, somewhere can create this eras version of Linux, hopefully under this eras version of the GPL.
