In your estimation, how much graphic violence should my operating system show me on a routine basis?
I think it's simple: the amount that maximizes the OS vendor's profits.
If you don't like this, you're free to choose a different OS vendor, or use a free OS, of which many variants exist.
Personally, I applaud Microsoft for doing their fiduciary duty and maximizing profits, even if that means pissing off their users who refuse to abandon the platform.
