Chocolate is among the products the FDA require constant lab testing from manufacturers so that lead in food children are likely to eat is monitored. Beyond this report coming from a questionable source its also using the CA prop 65 limits (everything that exists causes cancer), instead of the FDA limits, to claim they are bad and their data doesn’t agree with the FDA data.
The less processed chocolate is the more heavy metals it will contain though, dark chocolate will contain more than milk and nibs will contain more than dark.
