It seems to me that the obsession with this man’s commitment to yiddishkeit says more about the posters than it says about him. Many here have almost idolized him, or at least saw him as “one of us who made it to the top”. But the top of what? The goyishe pop charts?
Many posters have fallen into a trap that they themselves set. Those who ignored Matisyahu till now don’t have to waste their energy on whether he really means it when he goes to the mikvah. Those who wasted their time on this type of dubious entertainment till now should use their energy a bit more wisely next time.
