No, this is just saying the safe dosage level was biased by people from the industry being on that particular panel.

Despite the IARC’s new designation, the Joint FAO-WHO Expert Committee on Food Additives (JECFA), which determines safe doses of food additives, did not change its recommendation for daily intake of aspartame. JECFA still says that consuming 40 milligrams of aspartame per every 1 kilogram of body weight (about 2.2 pounds) per day is acceptable, according to a news release.

This is just 1 panel that determined the safe dosage level. This does not affect the findings of the study at all which concluded that aspartame is "possibly carcinogenic to humans" but that "We don’t know enough about the possible link between aspartame and cancer, but we can’t ignore that there’s something going on"

So they haven't even found a definitive link or even said it's definitively dangerous. And the 40 milligrams per 1 kilogram of body weight is the same as the recommendation from the FDA.

Also the thing it is replacing, sugar, IS known to cause cancer, diabetes, and other diseases. So take that as you will.
