I see them "bending over backwards" to protect their right to keep an advantage to use, if they deem it necessary, against any one else.
this is why they go to such lengths to avoid publishing what they consider to be "the secret sauce".
as I see things, that they even came up with the notion of a "software bill of materials" is a bit disingenious from my perspective. already the concept is obscure and lends itself (in my opinion) to shading, hiding, and occulting the software source code and (or) the hardware designs (as appropiate)
finally, I consider that the concept of "SBOM" (which TIL existed) is designed with the intentions I already mentioned: to occult information (anti-open) for the sake of keeping a perceived advantage (pro-centralization)
