Quite ironic as they base their business model on reverse engineering another product, and selling add-ons for it... and they don't tolerate a user giving away an update a users has made? The dubious ethics aside, I'm not sure if they have any juridistriction to do so, in fact, I'm pretty sure they don't.  

 

Of course they can if they so choose, and they do.  It was written into the EULA that you agreed to when you installed the MD-11.

This thread has run its course I believe.
