That is so blatantly wrong that I laugh out loud every time some one throws it in the mix. The boys from Apple paid Zerox for what they used, you might note that Zerox had not a clue what to do with what they had.
You should of course include in the mix how Bill Gates stole(Actually bought) the original DOS. He was clever enough to only license it to IBM and those Savvy old boys agreed to it.
Man, any way you cut it they saw a good thing and ran with it. Begged, bought, or stolen doesn't make a bit of difference, especially if you read the whole history of the company and the number of times it was nearly bankrupt due to silly crap they did to themselves.
have a nice day
