I was there. I watched Linux from the beginning, including the minix-list discussions.

The only thing Linus 'copied' (rather, modelled) was the initial directory tree layout and some of the names of the core module filenames - none of the code.

Linus was interested in MINIX, no question - and motivated to write his own kernel - but he literally did not fork MINIX.

In "History of Linux" this falsehood is addressed - and it has to be said is amazing that you are parroting even still today:

I challenge you to find the code, from MINIX, that Linus copied and then modified and called it Linux. This is what forking means.
