Apple is the developer of thunderbolt,They wrote the specifications for it and there are two thunderbolt ports on every M1 Mac

Intel invented Thunderbolt as LightPeak. Apple developed it further in cooperation with Intel.

You are right. I forgot about LightPeak, which was designed to work over optical cables.

Apple came in when Intel decided to build a version for standardized cables, and helped Intel develop the spec (and even supplied the name).

But my point remains. Apple knows Thunderbolt as well as Intel does by this time.
