Because Faculty are generally paid very poorly, have many courses to teach, and what takes up more and more of their time are the broken bureaucratic systems they have to deal with.

Add that at research universities, they have to do research.

Also add in that at many schools, way too many students are just there to clock in, clock out and get a piece of paper that says they did it. Way too few are there to actually get an education. This has very real consequences on the moral of the instructors. When your students don't care, it's very hard for you to care. If your students aren't willing to work hard, why are you willing to work hard? Because you're paid so well?

I know plenty of instructors who would love to do things like this, but when are they going too? When are they going to find the time to learn the skills necessary to build an interactive web app? You think everyone outside of comp sci and like disciplines just naturally know how to build these types of apps?

I could go on, but the tl;dr of it is: Educators are over worked, underpaid and don't have enough time in the day.
