This isn't Tor, being an exit node just means the non-techy user can access Netflix while travelling internationally.

Blame Tor for popularising the term "exit node" to mean "public proxy".

The terms "VPN gateway" or "VPN server" are still valid and less easily confused with Tor's use of "exit node".

Yes and no... A VPN Gateway or VPN server doesn't have to be an exit node, and may route onwards to actual exit nodes. Some nodes may not "exit" at all - see setups where you are just trying to reach your private networks.

In a tailscale setup, an "exit node" has specific meaning and the term makes sense as far as I'm concerned:

It’s not a public Tor exit node. It’s a personal node you can use to route your own traffic.

I have setup Pis in family member homes to allow me to get residential IP VPN exit node in their respective countries - cheap and easy way to get access to foreign TV streaming services without a monthly fee. I used to run my own exit nodes in AWS/DigitalOcean in those regions, but virtually all streaming services block VPS/cloud service IPs at this point. Having an exit node in an actual "real" residential internet service is vastly more flexible.

This potentially would be even easier for me, given they all have Apple TVs already. This isn't a public exit node - it's only available to other users (i.e. people you know and have granted access to) of your own TailScale setup.

Same for non-techy folks who have second homes in foreign countries, or even just travel a lot - an Apple TV running this new app back in their main property will allow them for free to browse the web as if they are actually at their main property, including any TV services they enjoy.

So that when they're overseas, they can route their internet traffic through their Apple TV at home in the US, and any streaming service they use will think they're in the US and not give them trouble about "Hulu isn't available in your location".
