Quoted from Utesichiban:The reality is Stern can only do so much to protect their licensees. It isn't as if Stern is trying to make code with the goal someone hacks it. They do their best and that is really all they can do.
If they go to the length that they require all owners to not only have good WIFI access but also be connected to get any code or other necessary updates required to keep home based machines operating correctly, they risk angering many customers and hurting sales in the long haul IMO.
With the amount of locations without WiFi I think you might be over worrying about this.
