You might have a point if I taught this course instead of offering knowledge and code for free, but I do it as well. Over the years I have contributed thousands of answers on R-help and hundreds on stackoverflow. I've written dozens of open-source packages and look after several R related mailing lists. I make pre-prints of all my papers available for free, I release all my lecture notes under creative commons licenses and I'm a supporting benefactor of the R foundation (or at least I've submitted the paperwork, I'm not yet listed on the site). What more do you want?! Some of the money I earn from these courses goes to pay for my summer salary and supports student research. It also gives me confidence that if I don't get tenure because I've been writing R packages instead of papers, I can keep doing the work I love.
