I think that's what this is about.
It doesn't mean aspartame is bad and we are all going to die.
It means that perhaps the safe limits, risk reductions etc need to be re-assessed for them to be with regard to actual harm reduction... instead of the current possibility of "just enough harm that coke doesn't get blamed, but good profit can still be extracted" that these coke associates may-or-may-not have influenced.

It calls recommendations into doubt as opposed to the actual raw science.
AFAIK, aspartame has been widely studied. If it was a substance of actual risk, it would have been highlighted.
