people dramatically slowing down then speeding up is likely more dangerous than everyone maintaining a speed higher than the posted limit, which makes the cameras a net negative from a safety perspective. Highways built for safety and limited speed differential across users is so much safer than limiting top speeds.

More dangerous to drivers (especially those inclined to drive at dangerous speeds), maybe. More dangerous for pedestrians? I'm not sure about that -- especially if nobody's obeying the limit in the first place, getting drivers to slow down at all is a good thing. Or do you like to have drivers speeding at 50MPH down the narrow side street (signed at 20MPH) your kids cross every day to get to school?

They're talking about freeways and highways, not narrow side streets.
