I totally agree with what you're saying. However, I'd like to point out that the initial intention with MOOCs was to lower barriers to entry for low income learners around the world. Adding a fee to certificates may have increased barriers to entry in jobs that require certificates now. This, too, may prove to be a trend for increasing charges in MOOCs ... who knows maybe in a few years you'll be paying a massive sum of money to take a course course.
