This exact code can be found 1000 times on github and many of those are MIT licensed https://github.com/search?q=%22cs+*cs_transpose+%28%22&type=.... Copilot, or any other developer or person, has no way of knowing where the original implementation came from or it's original license. The cat is out of the bag, get used to it.

Or just don't use Github.

Not using Github doesn't stop others from posting your code on Github with incorrect licenses. It becomes a massive game of whack-a-repo

Or just don't give a hoot.

Takes practice, but it's a skill that can be mastered like any other.

This may be an acceptable approach if the code is not produced in a professional context and not of professional quality. One of the keystones of open source is professionals have had an ecosystem where they can deliver value to an open forum but still have at least a semblance of control how their contribution is used via various licenses they can select.
