I learned that some education platforms use data mining application for marketing purposes not just educational purpose.

I have often heard of student information being leaked or used in adult business or scams of some sort, however, the how always eluded me. Learning that some companies not only use but sell student information to companies that use these mining apps to sell students and their parents things versus to make the app more useful for students is a bothersome thought. An idea that reconfirms that we live in a profit driven not people and purpose driven society.
