This is not about information but about capital. Even if we had free access to the weights of the best models in the world: who would be able to run them?
Well it would be anyone that has access to a datacenter to run them. Which is a ton of companies. And those companies will rent out access to those models. And if they do something stupid to screw over consumers, well the whole point is that there would be a bunch of companies that you could use instead.
Technology is deflationary. I am holding in my hand a device that would have been a supercomputer 30 years ago. It costed me a couple of hundreds of dollars.
These models and the hardware they are running on will get even more efficient. We are nowhere near the physical limits of what we can achieve.
