Performance degrades of course, but modern EVs are quite popular in e.g. Norway where they drive them well inside arctic conditions. It's not like they stop working under conditions where ICE vehicles definitely face challenges with both range and reliability. Unless your ICE vehicle is plugged in to keep the engine warm when it is parked, it might not even start at all. Those same systems are great for keeping your EV topped up of course.
Anything liquid might end up freezing. In an EV that's electrolytes, cooling liquid, brake fluids, etc. Of course, batteries can be heated in an EV and that helps. Simply using them heats them up. That's why many EVs have battery cooling. Also many owners might want to turn up the heat remotely so they enter a nicely warmed car instead of an ice box. That costs energy and range of course.
So, it's not all that black and white. But overall, it seems EVs can do well under arctic conditions. All the big vendors test under those conditions. The cold hard reality (to paraphrase the alarmist title) is that it isn't that big of a deal.
