Leo says whenever he's on communal Wi-Fi, as he will be on the cruise, a hotel, or a coffee shop, everyone's on the same network. Nowadays, places like these are getting better about making it more secure, and it isn't as risky as it used to be. But there is a potential risk that someone else on that network could snoop on him. Whenever he's using email, shopping on Amazon, or banking, all of that traffic is already encrypted. Leo thinks using a VPN on cruise ship Wi-Fi would probably slow his connection down to a point where he wouldn't be able to stream content online.
