Actually yes you should give the essentials away.

If you develop a platform that runs software, you should freely distribute necessary the tools to develop software for the platform.

The end user should own their device and that means they should be able to develop software for it free of charge once they have the device.

That does not mean that you can not make libraries that you sell. So I think apple could sell a specialized ML library for their chips, as long as they document the hardware such that someone else willing to do the work could also create such a library
