I would attend classes if tuition were gratis. Either way, I have the /option/ to attend. I am not excluded, unless the university requires students to have Facebook accounts, in which case I would protest on the basis that a right to an education and a right to privacy should be simultaneous rights.
This app would be useful if it did not have the artificially manufactured arbitrary requirement to patronize Google and share information with Google that does not necessarily exist (a mobile phone number).
