While a random WiFi network isn't what I'd love to join too, at least it's an option for receiving a code through an encrypted channel (push notifications). If that encryption can be MITMed, then there is a much bigger problem as any traffic can be MITMed at cellular network level anyway, voiding out any WiFi-MITM concerns.
