No. If the instructors wanted to put this up for free, they could build the course on Open edX, and put it up for free with any of the hundreds of free Open edX providers. They could license under an open license. There's nothing stopping them (including their university). They're asking us to crowd-funded a crappy profit-making scheme. The course will be of questionable quality. You don't learn math without doing math. That's a scientific fact. Their "free" offering is "audit videos." I'd encourage anyone to look up the mass of literature about interactive engagement versus passive learning. You feel like you're learning, but you're not. People basically would waste their time.
