Telsa support seem to have considerable remote access to the internals of powerwall gateways. Most people will likely have the gateway on their internal lan. If it's a wired lan, then the gateway has the potential to see all the traffic on the lan. If Tesla support got hacked, this would provide a path into the lan of lots of Tesla's customers, with the potential for doing considerable harm. Ideally the gateway would be isolated on segment of its own, to prevent it from snooping on traffic, and allowed access only to the internet, and such lan web traffic as its owner requires, but this is not something the typical owner will know how to do.
