That's not really true though, providers are deprecating models and I have at least 10 emails to prove it.
When the weights are publically available (and open to use), then there's a free market for hosting that model at least. That's not independence for me, but it's lack of vendor lock-in.
For some of the open models, there's a list of 20-30 providers of the same model on openrouter for example, as an example of the supply.
A provider deprecating a model doesn't mean the .gguf file disappears from my computer.
Nothing stops you from downloading the model and hosting it on a cloud virtual machine
