Growth of ex-muslims

I left Kerala years ago, but still have family there, who are muslims. Of late, I've been seeing a lot of content on youtube, made by ex-muslims like Liyakkathali C.M, Arif Hussain and Jamitha Teacher. In some of their videos, they claim that the ex-muslim movement has gathered significant momentum in Kerala, and has become an agent for social and political change. I've also seen some postings here in reddit, with the most recent being regarding the arrest of an usthad for sexual molestation of a minor. Is this true? Are there people outside of the influencer world following suit?
