Is there any reason microsoft doesn't bundle firefox with their operating system, and just EOL Internet Explorer? Despite common belief, MS actually wants the best browser in the world. But they want it to be noticeably the best. The fear MS would have if FF did their browser is that the FF browser for Windows offered no advantage over the one for Linux or the Mac. Or even worse, the Linux version of FF was substantially better than the Windows version. Now you can argue that IE isn't as good as Chrome or FF, but at least MS knows that's their decision. They've allocated their resources and made their business case. If FF is providing the browser then MS could end up in a situation where the most visible end user feature is out of their control. Let me flip the question on you. Do you think Apple ever would/should simply let FF or Chrome be their iOS web browser and stop doing Safari mobile?
