It turns out that these ex-muslim videos put up by christians are totally fake. Any Muslim who has basic knowledge can spot this. I suppose its because they cant accept the fact that the videos of christians becoming muslims are actually genuine. I agree that some of the videos are difficult to refute due to the reason that they have been extra careful to not make errors. But a Muslim of very little knowledge can see that all the stories they produce are the same and fake – they play some arab music in the back, then the music of "light at the end of the tunnel" plays.
