> Meta could change the license of future releases of Llama and kill your business built on it.
If you built a business on Llama 3.1, you're not going to suddenly go down in flames because you can't upgrade to Llama 4.
Even saying you really needed to upgrade, Llama 4 would be a new model that you'd have to adapt your prompts for anyway, you can't just version bump and call it good. If you're going to update prompts anyway, at that point you can just switch to any other competitor model. Updating models isn't urgent, you have time to do it slowly and right.
> If the training data was openly available, even if you can't afford to res train a new version, a competitor like Amazon could do it for you
If Llama 4 changed the license then presumably you wouldn't have access to its training data even if you did have access to Llama 3.1's. So now you have access to Llama 3.1's training data... now what? You want to recreate the Llama 3.1 weights in response to the Llama 4 release?
