So Opera is free now, it was paid before.
Again, as I pointed out IE is a windows only program. That doesn't mean you are paying for it by having to buy windows. Look at any free windows only program out there on the web. Does Microsoft pay them considering you have to buy windows to use it?
Google Earth is windows only i believe is it now? Does that mean you pay for it considering you had to buy windows? Do you think that Microsoft gives Google a certain percentage of the money made on every windows licenses?
in fact it is also available for OSX
