I really don't want to set a precedence of charging students for something I don't think they should be paying for. I'd rather have them keep their money so they can help improve the world in their own way.

Worse for who? Society? I don't believe it is my job to fix societal problems. I can help in a way that makes it fun and interesting for me and if any of the graduates want to continue providing the service and charge 5-20% of the students pay, they are free to launch their own service. Everything is open source.
