From my reading the disagreement is about how often or much chocolate people consume. The thresholds (MADL, EU) are in µg/day and the Consumer Reports numbers are in µg/serving.
Arstechnica somewhat bridges this gap at the end with quotes including "at these intake levels", "A single serving", "from time to time", "indulging during holidays".
The issue with lead is you can have a sub clinical amount from a dozen or even a hundred sources and end up with significant issues. Thus the threshold needs to be set extremely low for any individual source.
Arstechnica is really understating the risks here. While global chocolate consumption is 7.2 million metric tons that isn’t split evenly among 8 billion people resulting in 1.8kg/person per year instead the majority of the global population is 0-0.5kg/person and the rest is increasingly concentrated.
It’s not that uncommon to find someone eating a 1.6oz Hershey chocolate bar per day or the equivalent amount in whatever brand they prefer. If they happen to like an unusually high concentration brand the amount on its own might not seem concerning but it combines with every other source in their life and their lifetime accumulation from other sources.
For someone in the upper 1% of chocolate consumption, lead intake via chocolate is unlikely to be anywhere near the top of their list of health risk factors.
It could easily be the largest risk factor from chocolate.
In Switzerland the average person is consuming 8.8kg/year (22lb), and the country is quite healthy by international standards. They have the lowest obesity rate in Europe and and half that of America which averages significantly lower levels of chocolate consumption.

Glad to see my Ars ban in 2015 was ahead of the curve, and sad they are still churning out the same garbage that got them blacklisted in the first place.
Not all chocolate is sweet. I would claim that none of the good stuff is. The bars I used to eat, before stopping for the heavy metals, had 7 grams of sugar.
I used to eat a large bar of very dark, high quality, chocolate per day (having to constantly explain to onlookers that the whole bar had the sam sugar as a half cup of milk). I’m sure I was in the 99th percentile for cocoa. I stopped when I saw this coming a few years ago.
That's me exactly. I used to eat half a bar of 85% - 100% dark daily. The (relatively) recent info on heavy metals has me really bummed. Why is everything always so toxic these days???
My new goal is to figure out how to get all this heavy metal accumulation out of me (I've been eating heavy dark chocolate regularly for years), and find ways I can keep eating chocolate without absorbing more. Some studies I've read mention that tomatoes might help prevent heavy metal absorption when consumed with the source.
