He basically explained how Bill Gates got his money, from IBM, to get into his PC business empire.
And about how Gates afterwards went to court and sued IBM because he said it was his code while in truth 100-500 people actually helped him to build the knowledge to actually do it.
Andrus claims that Bill Gates was at that time an Opportunist and that IBM should have handled it differently because there was no official contract given by IBM, which is why they ultimately lost in court back in the day.
I am actually in fav of IBM in this case and would rule for them, the entire thing was more depending on the fact that they did not made an official contract, it was purely a handshake thing, which was back in that time not special but Bill Gates saw his chance here and he knew he might win in court because of that.
There are also interesting videos about the whole court process and there are some interviews on YouTube framing Gates as liar but this is another story which I do not want to go into because that is something I do not want to show here nor was I involved into this.
