Bill Gates copied Gary Kildall's operating system:

Questions: 
Why would IBM give Bill Gates a huge advantage by pricing his operating system at $40, while Gary Kildall, whose operating system Gates copied, was priced at $240, which obviously made sure that Gates' copied OS was selected over Gary Kildall's OS, even though his OS was the original?

Did it have anything to do with the fact that Bill Gate's mother was a friend of the CEO of IBM?
