My dad wrote software in the 90s and developed a pretty good name for his business. He once got a call from Microsoft saying they wanted to package his software in their newest OS builds. Holy crap, right?! That would be a major break!
They told him they needed to do some deep interviews to set the plan in motion. I can’t remember if there were supposed to be 4 calls total or if it was on the 4th call, but after a couple conversations my dad realized the questions they were asking were to reverse engineer his software. They were never trying to make a deal; they were trying to learn what they could so they could rewrite it and not pay him a dime. He told them to pound sand.
There were a few other conflicts he had with Microsoft. I was young and didn’t understand it well, but my whole childhood I knew Bill Gates led a shady as fuck company and thought he was an awful POS. It honestly still kills me to admit that he (now) does some good in this world.
