I really don't think the Jacksons would keep us wondering if MJ is alive or death because of money reasons. Because we, the believers, aren't a huge percentage of MJ's fanbase and we're clearly not spending any money investigating that goes directly to them. I think the fans that believe he's dead spend money too buying his CDs, DVDs and memorabilia. But yeah, it is at least suspicios that none of the Jackson has adressed the matter of the theories of the death hoax.
