Of course, some people are outraged over this. They think it's exploitive. The idea of having a homeless person wear a t-shirt that says, "I'm Jonathan, a 4G Hotspot." is a bridge too far. I guess, in a way, I thought this, too. Then I realized that the homeless person keeps 100% of the money that is donated to get the password. And before you decide that people would just share the password and shut out the homeless person's ability to make money, the passwords are for 20 minutes of Wi-Fi. People would need to re-up. That could add up. The person could make a nice bundle of cash.
