Why is fire fox free

Here's my spin on it.

There are still decent people in this world, whom do somethings just for the love of it. They believe in the sharing of their skills, and the helping of their fellows because they are in a position to do so, not because they can make a buck out of it.

The programmers whom develop freeware are no different from charity workers, or volunteers who help out at disasters, that just have a different skill set, and give to society in their own way.

I for one thank them for their generosity.
