Seven Of Nine is Brannon's creation, he can do what he wants with it.
Furthermore, Seven Of Nine is not his ex girlfriend, Jeri Ryan is.
Jeri Ryan has played a lot of characters besides Seven Of Nine.
Furthermore, Seven Of Nine is an iconic character in Star Trek like Data. Any featuring or display of Data is not the same as pulling the strings of Brent Spiner.
Your hatred of Brannon seems to go far beyond normal criticism, and delves into something spooky and personal.
