This concern is only valid if Noah himself is the one who committed fraud but for a normal employee of a business that once provide a legit service this accusation is totally unfair just because he work on FTX.
So far Shuffle doesn’t have any existing scam accusation and provides solid service to all its customers. I think it’s not a big deal his background if his current company is operating well. If Shuffle was owned by SBF then I will agree that this company needs a thorough investigation.
