If you read the article, you’ll see that the universities in question have already, voluntarily, given partial refunds to students prior to these lawsuits.
The lawsuits are demanding even more refunds while the students still want to collect the remote education. If the Universities were faced with this decision up front, it would have been better for them to furlough all employees and simply delay education until after Coronavirus.
Instead, they made the best of the situation and tried to do right by the students as best they could within the financial, legal, and ethical constraints of Coronavirus. In my opinion, it’s not reasonable to demand universities operate at a loss to provide the remote education at a rate less than it costs them to operate (which I suspect may be happening already in some cases). We’re all making compromises under the circumstances.
I’d be more sympathetic if these students were requesting to defer their education until after Coronavirus and were willing to forgo all education and credits in the mean time. Demanding both the education and a refund isn’t exactly fair.
