I dunno, once you're dead nothing else really matters anymore, does it? You're not a person anymore, so why would your opinion matter? If my family can use my legacy to make money for themselves, I would just be happy knowing they'd be a bit better off once I'm gone. And if they choose to protect the right to use my voice/likeness after I'm gone, I'd prefer that they do so because of their own personal beliefs, not because they believe they have to do so for my sake.
