Why does it matter? No company is going to do nothing if someone else distributes a modified versions of their software -- regardless of the modification. The fact that it's cracked or not is inconsequential to the discussion.

You still have a point, but isn't what you declaim precisely what companies like RedHat, Canonical, etc., do. Mozilla, and Google too, to some extent.

Free software licenses are specifically designed to allow distribution -- the exception that proves the rule. But even so, none of the companies listed will allow you to distribute modified binaries under their exact product names. Hence CentOS, Iceweasle, etc. Despite being open source and free software, these companies still want to define for themselves what "Firefox" and "Redhat" actually are.
