First off, he was a genius and an amazing artist.
BUT, make no mistake. He was also part of "the machine" and a brilliant marketer. He was not above selling any more than The Greatful Dead were.
So for his fans to take this so personally is ridiculous. He wasn't a God. He was a man. And he sold a zillion records and was rich. He was a capitalist. He died with a net worth north of $40 million. So he wasn't opposed to making a dollar. And he likely wouldn't oppose some friends and family touring and jamming with his likeness.... or turning a profit while they did it.
Anyone stop to think about the musicians? Maybe it would have been fun for Zappa's kids or Steve Vai to get a chance to act out being on stage with Frank again.
But, no. We gotta get our collective panties in a wad and ASSUME that we know what Frank would have wanted.
The (insert inappropriate language here) internet has become the quickest way ever for a mob of idiots to grab up torches and pitchforks. That's about all it's used for these days.
Gimme a break.
