Something has been on my mind for a while, why do Apple, Firefox, and others want so many people to adopt their bowsers and have such high market share? The browsers are free, so it's not like they make any income, and they probably spent a lot on R&D. What real benefit to Apple, Mozilla, and Microsoft have by making and promoting Safari, Firefox and Camino, and Internet Explorer, respectively? I could kind of understand why Google wants you to use Chrome, it integrates well with their online services and ad oriented. Is there something I'm missing here?
