Windows vs Linux

I was thinking about the the same old war between Windows and Linux and how Bill Gates is making immense amount of money.Also abt why MS is very secretive about the source code.As everyone knows once the source code is out windows will lose its charm as coders will make a new OS including the best features of both Windows and linux. My stand on the issue is that you never get the recipie of food stuff bought from the shops.Why even many hotels and even women are so secretive about their 'secret recipies'?Then how can you ever expect MS to release the windows source code. Ofcourse windows has lots of bugs and all that problems.By Bill Gates is not forcing anyone to buy windows.The best thing possible is to reduce prices drastically which can very well curb piracy.
