"Coupled with this are the salaries that he continues to receive from the shows and other media that hes still involved in. For example, Nick Cannon earns an estimated $70,000 per episode. Alongside this, he receives an estimated yearly salary of $4 million from Husbands of Hollywood, which is quite a significant sum. Estimates suggest that Cannon receives $10 million in yearly salaries from all of the work that hes involved in. However, its unclear as to whether this includes royalties from various other shows and musical avenues that hes no longer involved in."
He's still involved in things. This should be reported about and he should be cancelled immediately. People he's associated should be submitting statements that they're appalled and disowning him. Any show or employer or artist he's involved with should be severing all ties. This would be happening to any other person right now, but of course as others have pointed out, this type of racism doesn't seem to be treated as seriously as it should.
How many cases do you know where royalty payments stopped being made?
But yes, any work he continues to do should be canceled.
