That only works with public hotspots. How many firesticks are connected to one of those?

Not at all correct. Many home WiFi hotspots are recorded by MAC address with their (approximate) location. So all a device needs to do is see one hotspot (public or private) and you can get a location within 50m or so. Add a couple of neighbours and you can get quite a good location.

The device doesn't even need to connect. It's enough to see the broadcast SSID advertising to see that MAC address.

They use summary of all the networks. You can add your own matching some other location, but you can't subtract your neighbor's networks.

One could generate some interference (with NRF24L01 or similar) to block out the neighbor's networks, with the power very low to limit its range.
ataradov:
Sure, but it does not sound too reliable, plus you would affect your own network too.
 
This can't be productized for the masses, and I don't think they care if a couple geeks jam their own network to spoof the location.

It may be easier to just have it in a Faraday cage with just one access point. This way it will only see the notwork it is meant to see.
NiHaoMike:
The jamming could be at such a low power level (fraction of a milliwatt) that it basically has to be attached to the back of the device.

I suppose just putting it in a metal box along with a Raspberry Pi would work. But then why not just use the Raspberry Pi as the media player? (I suppose one could use a Raspberry Pi Zero, plenty powerful enough to use as a VPN router and cheap, but only limited to 1080p graphics.)
