Thank you for the book recommendation 
In case anyone’s curious, I looked it up and found this:
Paul Allen negotiated an agreement with SCP [Seattle Computer Products] owner Rod Brock in January, implying that Microsoft had a whole stable of customers eager to run 86-DOS. The deal would essentially allow Microsoft to act as middleman — or, if you like, retailer — in these transactions. For each customer to whom they sold a license for 86-DOS, they would pay SCP $10,000, or $15,000 if the license also included the source code. They would also pay SCP an initial fee of $10,000 to begin the agreement. For SCP, a much smaller, hardware-focused company without the reach or marketing skills of Microsoft, the agreement sounded great — especially because business lately had not been particularly good. Microsoft seemed convinced that they could sell quite a few licenses, bringing in effortless money for SCP for this operating system Paterson had begun almost on a lark. One clause buried in the contract might have raised a red flag: “Nothing in this licensing agreement shall require Microsoft to identify its customer to Seattle Computer Products.” Brock later said, “That seemed strange to us, but we agreed to go along.” In reality, of course, Microsoft had no stable of eager licensees. They had just one, the biggest fish of all: IBM. Microsoft sold just one license under the agreement, acquiring IBM’s operating system for them complete with source for just $25,000. […] MS-DOS, purchased for [a total of] $50,000, was earning Microsoft more than $200 million per year by 1991.
I think that’s contrary to principles like win-win or informed consent—let alone something like TCS-style common preference finding lol. (It reminds me of the idea of creative adversaries which I think is a great concept/discovery.)
I initially thought that both Apple and Microsoft copied Xerox, but looking into it, it seems that Apple made substantial innovations:
Jobs’s software team took the graphical interface a giant step further. It emphasized “direct manipulation.” If you wanted to make a window bigger, you just pulled on its corner and made it bigger; if you wanted to move a window across the screen, you just grabbed it and moved it. The Apple designers also invented the menu bar, the pull-down menu, and the trash can—all features that radically simplified the original Xerox PARC idea.
Whereas Windows 1.0 didn’t even have proper windows. And when Microsoft added proper (Macintosh-like) windows in Windows 2.0, Apple sued them.
Yikes. Looking it up, it seems that Apple only settled because they were on the verge of bankruptcy in 1997.
I suppose this is an instance of planned obsolescence and another example of Microsoft trying to get money “without providing big value or having any big accomplishment.”
