Unethical practice of selling knowldge

 A MOOC is a web system for learning. Because of COVID, because many people worked remotely and stayed at home, such websites have increased their subscribers. Along with the number of learners, their revenue skyrocketed. 

One of the major MOOC systems, EdX sold itself and is no longer a non-profit.  

Should we pay for the learners, or should the learners pay for education? If the learner must pay, should who is getting their money? The state? The universities? The administration? THe Democratic Party? Does Obama own the website because he knows the CEO? 

Supposing monopolizing knowledge gets them the money. Should it be carried out by -- whom? A local party chair?  

Is giving the first class seat for the paid subscribers ethical in terms of the party politics?
