"'The formation of the Mozilla Corporation gives the Mozilla Foundation new capabilities for becoming even more successful in delivering innovative open source end-user products," said Mitchell Baker, president of Mozilla Corporation. "The Mozilla Corporation is not a typical commercial entity. Rather, it is dedicated to the public benefit goal at the heart of the Mozilla project, which is to keep the Internet open and available to everyone.'
The broad adoption of Mozilla Firefox has created significant economic value both in Firefox itself and in a commercial ecosystem that is developing around Firefox."

Is the delivery of "end-user products" not the source of revenues for the Corporation? What if all those products are delivered for free? Then where do the revenues come from?
Giving away free software while still producing significant revenues from commerce seems to resemble the other corporations that deliver web browsers and other free web software. Regarding those companies, it has been said that "Users are the product".
Note I am not implying anyone has done anything wrong. Each party is expected to pursue its own self-interest. Freedom of choice is a necessary component of an "Internet that is open and available to everyone".
These are just some facts that I believe could be relevant to users who are not interested in marketing user data or the advertising sales ecosystem.
