It was already relaunched once, relaunching it once more would've irritated a lot of miners who were standing by ready to mine already having been through one canceled launch. Would it have been the correct decision in retrospect? Yes. Then why wasn't it? Maybe Evan didn't want to irritate those people anymore than they already were. Maybe he thought it was no big deal as he never could've imagined how big the coin would grow and didn't realize the extent of the problem. Or maybe the other dev team member opposed another relaunch. Or maybe it was an elaborate scam of theirs. Or something else. Take your pick.
