How demoralizing do you think it is to be paying a fair bit of money (or more likely taking on a fair bit of debt) to be just 1 of 100+ students in a poorly functioning online class?
To be clear, I'm not blaming the teacher here but the system has continually failed students. It's become a stupid game that you pay a lot to play because you have to. When I was younger I used to very anti-cheating, but I realized with time that was a foolish principle to hold on to. The game is rigged and there is no shame it taking short cuts. The university is trying to exploit you the student so why would you not return the favor and seek to exploit the system whenever you can?
Consider the counter position: what would an incredibly passionate, engaged and hardworking student get from this situation? This experience for that type of student is scarcely better than just teaching yourself from a text book and free online lectures (in fact, all of the material for this class is free online)... only you don't get a degree doing that.
My only critique of the teacher here is not having a enough empathy for these students and spending far more energy trying to catch cheaters than address the fact that these students have gotten a raw deal. Ignore the cheaters and spend those extra hours chatting one-on-one with the students that actually give a shit (if there are any left).
