why no aol for linux?

I have wondered why aol has not produced a product for linux users. Since AOL has an apple version, it should not be very difficult to make a version for Linux. The graphics part should be able to work with xwindow without any problem.

Even if AOL did not want to port the aol software, they could still provide a connection like any other isp; Linux users could then use the web to get to their mail, etc.

I don't see any big conspericy or anything like that; I suspect aol does not appreciate the size of the market.
