That's not what the article says. The article doesn't even state the problem.

The actual problem is that cold batteries have higher resistance, so these cold cars aren't charging. The owners need to run the heaters in their car for 30-45 minutes before they try to charge to be able to effectively charge at all.

Right if everybody's range is reduced (due to cold) and charging takes longer (to warm up the battery, if it wasn't warmed before arriving, which could either be user error or due to a car that was parked nearby outdoors before being taken to the charger), then the effective capacity of the chargers is reduced by a large factor and quite possibly people are running out of battery waiting for a spot. I suspect a large fraction are Uber drivers who may not have a spot available ti charge at home.

How could that conceivably be user error?

based on what I've read (I have never driven an EV...) you're "supposed" to "precondition" (i.e. warm?) your battery before charging if it's cold.
