Unlike others here (based on the downvotes), I don't think your concerns are entirely unfounded. Google is a classic example of a company that scorches the earth with their freeware releases - remember Kiko?

But ultimately, whatever is best for the consumer needs to win out. If freeware knocks out commercial competitors then stagnates (like Internet Explorer), that's bad, and analogous to dumping which is not legal.

If it's just better product and continues to be, like Google Calendar, the world is simply better off.
