Oh, by the way, the person with the device has to have received one that wasn't already tied to THEIR account in any way. You know, like by the automated system that sends these things out reading a barcode on the side of the box that associates device IDs with a particular account. Not sure about anything else but this was the case a decade ago when I bought my first Kindle. I'd imagine it's a bit more sophisticated now.

Go hang around a random apartment complex with wifi sniffing boxes and see how long it is before someone tackles you.

Honey, if you think a wifi password is needed to pivot to a network then you don't know what the word pivot means. At that point you're fucking BREACHED, BITCH. There's no pivoting, only ownership.

Ah yes, just jailbreak the Amazon device with phantom software that somehow has completely different checksums but still... has the same checksums.

All of this just illustrates you're an ignorant-ass that doesn't know how any of this works, wringing your hands about scenarios that DO NOT EXIST IN THE REAL WORLD.

If I absolutely need to get into your network I'm not fucking around with a fucking rooted Amazon FireTV I'm just going to CRACK YOUR FUCKING WIFI PASSWORD DIRECTLY.

Apparently I have all day every day to fuck around so why do I give a shit about it taking a week or two?

More likely, I'll walk up to your door with my phone in my hand and go "Hey, I just moved into the apartment next to yours and the wifi up at the office is broken. Could I log onto yours for a moment and pay a bill real quick? I apparently don't get any damn signal here either. I just moved from a fuckin' building where I had no signal, you'd think they'd have figured it out by now!"

And almost every time this will be more than enough.
