reverse DNS is problematic for exactly the reason you allude to, namely that ISPs rather than domain owners are in technical control, which puts small users (I is one!) at a big disadvantage. For these reasons rather than rDNS Caller ID instead uses a new forward query to the domain purportedly responsible for a message. If you can admin your incoming MX records, then you can admin your Caller ID outgoing info: the control is in the same place. You can find gruesome details from http://www.microsoft.com/spam.
My personal opinion is that you are not reading this correctly, and are indeed reading too much into this. I cannot and so will not attempt to reinterpret the actual contents of the license, but I suggest you give it another careful reading.
