This is equivocation - parent was discussing the founders' integrity in the sense of whether they are running a scam, not the broader moral integrity of developing this technology. While I am dubious about commercial supersonic flight (at least without significant investments in reducing emissions, though avoiding afterburning should already help), improved designs will at the very least lead to developments in the field, and possibly in related fields such as suborbital flight and spaceplanes.
