We’ve all been there – you need to get online but you don’t want to use your data allowance. You cast an eye over available WiFi networks: locked, locked, password-protected, paid access. Suddenly up pops an open, free network, simply asking you to agree to a few T&Cs for access. Too good to be true? It certainly is, as the people of London found out recently. As well as sharing all of their personal data over a WiFi network set up by security firm F-Secure, several people agreed to a rather unusual clause hidden in the small print: giving up the right to their first-born child. We assume that the company doesn’t plan to collect, but indentured corporate slaves could be just around the corner.
