I think it matters quite a lot, but not for scientific reasons.
If the point of origin is sloppy lab practice (maybe it's impossible to not be sloppy) and everyone lied about it, I want to know everything. Trust is a hard thing to re-gain but I really want to know where we all stand. Realistic calibration of your position vs. power centers is always a good thing.
Personally I don't think responses were particularly botched, although it's tempting to think so for other political reasons. It's likely more a lack of real knowledge by anyone on what really makes for good public policy and the inability to do what it takes in any case.
