The only people care about that NFT refund is those who got affected by the downside of the NFT price. I am not saying that he should not do the buy back initiative because he must have promised his audience about this and they have the full right to take legal action if he doesn't want to compromise his promises. But NFT investors should also keep in mind when investing in a project is that a influential person is behind a project that doesn't mean it can only generate profits.
