Tucker wants to use a captive portal wifi hotspot, but is it secure? Some are poorly made and can leak your data, others can sell data or even input advertising into it. Is Opera a good one? Leo says it's not exactly a VPN, and by giving away the service, that costs money. So they have to be making money somehow. Also, it's not strictly a VPN, it's a proxy service. One thing that Leo recommends is the Tiny Hardware Firewall. It has a built-in webserver, dual wifi radios, and a built-in hardware firewall.
