Bill Gates got rich by understanding that people want to write their own software. I'm not sure Jobs ever understood that.

Granted, I won't try to write a paean to Bill Gates and his business practices over the years, but I think his enthusiasm for user programming is one indulgence that I'd grant him.

The OP explains a specific example where Bill Gates took away user programming in order to screw over Apple.

Bill Gates got rich by getting a sweetheart deal (arranged by family connections) that paid per installation of DOS.
