Leah Remini and other celebrity ex-members of the church have changed the way the public perceives the religious organization. Per US Weekly, Remini and fellow actress Laura Prepon have very publicly left the church and revealed secrets that the organization hoped to keep hidden.

Prepon, who was an active member of the church for several years, recently announced that motherhood changed her view of Scientology. She told People, "I'm no longer practicing Scientology. I've always been very open-minded, even since I was a child. I was raised Catholic and Jewish. I've prayed in churches, meditated in temples. I've studied Chinese meridian theory. I haven't practiced Scientology in close to five years and it's no longer part of my life."

A source told US Weekly, "These are tough times for the church. Years ago, it [was] almost unheard of for a Hollywood star to openly walk away. But the tidal wave of backlash generated by the likes of Leah and other whistleblowers has changed that."

Between celebrities leaving the church, Remini's revealing television series, and the trial of Danny Masterson, Scientology is not in a good place. Whistleblowers like Remini and Prepon may have altered Scientology's future success.
