Netflix is going start charging extra for logging in outside of the home. Netflix is finally going after password sharing. Here’s how it’s likely to workIt's your responsibility to log out of the account when you check out. It's been a few years since I've used it but I seem to remember that there's some mechnism that when you check out, it logs you out, but I'm not certain. I get your concern about forgetting to log out and being at the mercy of the next person to use your credentials. I thought about that too. And yes that's a real concern. My point is, it's being done and it's certainly a way to access ST outside of your home, if you wanted to. The technology is certainly available, and on a massive scale.
And yes, with 4g and even 5g available, maybe the need to log into a bar's WiFi might not even be needed (though it would probably be more robust than even a 5g signal which is dependent on location.)
