Re: Only 45 years late?
I'd be careful what got revealed if I was MS. Perhaps there are too many skeletons in their closet from code they 'borrowed' from others? Little of what they initially did was original.
I forget which of my techie history books it is in, but IIRC the first thing Gates and Allen did after deciding they wanted to write a version of BASIC was to go get the DEC BASIC manuals from the uni library and start copying them. NT also borrowed from DEC. MSDOS was just a rebranded QDOS which itself was an unauthorised rip off of CP/M-86 by Digital Research. The Windows GUI was borrowed from Apple after they themselves got it from Xerox PARC. Etc.
I'm sure there are many more examples of MS 'borrowing' whatever they thought they could sell.
