I think people underestimate this issue. One of the reasons Windows is so dominant in the business landscape is because it's the OS people are used to since early years, mostly because it's bundled with most PCs people buy, but kids love to play games, and while a lot of games also come out for mac these days, Windows is still dominant in the PC gaming market.
It's a bit of a reach to say this, but it's a little bit similar to McDonald's selling toys with meals to entice children.
