I like that these companies will name their products OpenShell or OpenVINO or whatever with the implication that anyone else will ever contribute to it beyond bugfixes. The message is "Come use and contribute to our OPEN ecosystem (that conspicuously only works on our hardware)! Definitely no vendor lock-in here!"

It's not something like Mesa. It's open source in the same way chromium or android is open source. A single company is the major contributor and decides the architecture and direction the whole ecosystem will go.

What are the odds that Intel would ever use any of this open source Nemo stuff or vice-versa? If they do, it would be a complete rewrite that favors their own hardware ecosystem and reverses the lock-in effect. When you write code that integrates with it, you're writing an interface for one company's hardware. It's not a common interface like vulkan. I call it the CUDA effect.

You don't have to suppress a cure, you can just choose not to release information that reveal one or spend research money in directions that lead to a cure.

Also, not that vast if you consider the amount of people who have the information needed to realize what is going on.
