Re: How much?
Almost all corporations (not just Microsoft) are busy offering totally secure functionality even though this requires additional update payments from users. This is very good because they offer a lot of support to their users when the hackers start working to break into their applications and functionality. Imaging how much the corporate income would go down if hacking was stopped - we're seeing hacking increase every year now, and corporate income going up too, hackers seem to be making everyone (except themselves) very wealthy.
It's the same environment we see in the USA, people get shot around towns all the time and we're told that the bast way to stop this is for everyone to buy more guns, and walk around town with a pistol in their pocket.
