Internet myth?
My 2018 manual says Mopar plugs only @100,000 miles.
Thats my plan.
The guy had a screen shot from NGK. Went to their website myself with the part number and sure enough it was there.

Maybe it is due to them being aftermarket quality versus production quality. That is the case with many products in the medium and heavy duty world.
Not sure why guys are changing at 30K with no issues? One guy was at 83K and was changing because he stumble onto the thread. Didn't sound like he had any drive ability issues.
People change a lot of maintenance items like filters, fluids, belts, valves, and so on before any signs of drive ability issues.
However, that was not my question. My question was...."I have been hearing chatter in other forums that NGK, the company who makes the spark plugs on the 6.4L, recommends changing out all 16 spark plugs every 30k miles. Is this true?"
It appears by NGK's website that it is true unless that is and aftermarket plug and not the same spark plug as OE production plug as I stated.
