He's saying "We don't give a fuck about Dwayne Johnson, we only care about government regulations."

It is true that according to IARC, glyphosate may cause cancer. So does coffee. In Johnson's trial, the plaintiff originally alleged that the glyphosate in Roundup caused the cancer. When the defense demolished that claim using actual scientific studies, the plaintiff moved the goal posts. Maybe it's not the glyphosate, maybe it's the solvent, or the surfactant. Or it's actually a synergystic effect of all three.

Yeah, right. That's, like, a totally proven link.
