I don't understand how the owner intends to compensate the clients if all the data is destroyed? In addition, the deadline he gives is only 10 days, which means that he aims to ensure that as few people as possible manage to claim their funds - an old trick of scammers who try to justify their actions.
It's definitely exit scam, i bet they can't show formal report from the recovery company. The form itself is also ridiculous since they ask for Unique ID (which most people don't bother to remember).
Looking at this review, SM2258H is still used by SSD producer in 2020. So it's impossible there aren't any data recovery company which support that chip.
