Well the Shark Tank reputation has been tanking in recent years, with all their stars getting involved in all sorts of shady deals around crypto, real estate and training dealings outside of the show.
Kevin O' leary for example advocated for Bankman Fried all the way to his prison cell, and a number of his crypto companies like WonderFi(branded to his moniker) had Bankman's backing before hiding it after Sam got exposed.
Some sharks ran real estate "camps" with false adverstising where it was implied they would be there, but they never turned up etc.
List goes on, but it was smart of Cuban to jump off the sinking ship.
Held isn't the right word, he tapped it for sure.
