They didn't print it. They don't make the final decision to reprint it (or not reprint it). In all likelihood, they don't decide if it gets banned or not. (Even if they did get to be the call on if it's banned or not, how would you like to be the one who has to deal with all of the rage-filled emails from people who paid $500+ for a playset of them, only to have it banned?)
The card itself and the situation in which it has been released probably isn't the best, no. But you're blaming the wrong entity for it.
I've haven't played any games using a sideboard in recent memory - I played a tiny bit of MTG last year but never in non-casual (so never used them), and haven't played YGO in years and years, so honest question: in games that allow them, do you have to reset your deck back to what it originally was for game 1 in each match? Or is it more or less a free-for-all where you have X cards and you can pick what your deck is from that total card pool (within the constraints of the deck construction rules, obviously) for any game, no matter when it is?
