The owner of the company seems to side with the users. He sees the inclusion of the EULA as mostly pointless. He does see why Mozilla is requiring the inclusion of the EULA, but calls the decision “unfortunate.”
For anyone else who uses Firefox, we're used to that – you agree to the EULA when you install the browser. At the moment Mozilla is not commenting on why they made this decision. It is worthy of note that Mozilla's interest here is not in protecting the browser itself or the code behind it, but merely their trademark – that is, the Firefox name.
