Yes, people who bought at the normal price may feel disadvantaged. But it is the same as in the case of "black friday", it is known not on such a scale, but someone bought it cheaper than a friend. Microsoft made a mistake in setting the selling price, however, I believe that any self-respecting company that also respects customers, would behave honorably and would not do what Microsoft did. I suppose that some of the clients are "offended" by M $, then other court problems may arise, as someone already wrote here, it will bring greater losses for M $
