1. Right now, no one can access it. It's apparently not operational. Even if someone could access it, only Hughes knows the hidden SSID. 2. Again, it can't access other wifi connections. And even if Hughes were to do so, they'd have to be within radio range of it. Considering that they are routing your data within the satellite network and could access the modem remotely, driving to your house to do something nefarious with your modem would be unfeasible, if not practicable. 3. They've provided the explanation that it's for future use. They don't have to be more specific if they're not charging you extra for something that wasn't there before. Right now, it's just an undocumented innocuous feature that's most likely just being tested before they roll something out later. As I've mentioned elsewhere, I still don't understand what the furor over this is. It's completely inert and harmless. Unless it's impacting the service you're paying for (which it isn't) there is absolutely zero need for concern, nor to imagine it impacts your security. When they are ready to tell us what it is they will tell us, but there's no point in describing a potential feature if they've not even decided it's feasible to implement it. Then they'd be accused of bait n' switch: "So where is this such-n-such you promised us....", "you said we'd have this-n-that...", "you didn't produce...." See my point?
