Kinda. Since you can self-host the model on a linux machine, there's no meaningful way for them to prevent you from having the trained weights. You can use this to bootstrap other models, or retrain on your own datasets, or fine-tune from the starting point of the currently-working model. What you can't do is be sure what they trained it on
How open is it really though? If you're starting from their weights, do you actually have legal permission to use derived models for commercial purposes? If it turns out that Meta used datasets they didn't have licenses to use in order to generate the model, then you might be in a big heap of mess.
