It's just made up nonsense. Broke jealous people can't comprehend another person being successful so they come up with this weirdo shyt to make themselves feel better. Notice how it's always centered around black celebrities.
It takes a truly depraved individual to exploit the tragedy of another person's death and turn it into a conspiracy theory. "He murdered his mother for fame"

man get the fukk out of here. Can you imagine how retarded that sounds? "Now all you have to do is allow one of us to murder your loved one, and you will get the record deal/acting contract. It's just that simple. Every celebrity does it, and we somehow get away with the murder every time."
In some occasions a person's moral code will be tested like being asked to be a sellout or work with racists/Republicans. A label exec or celebrity with power might ask a female artist or actress flr sexual favors in exchange for a push. But that's about it. And plenty of celebs say no and still turn out successful.
