I like this move from google. Sure it is targeted for you to use Tensorflow but more courseware and MOOCs help everyone. I love doing self study and Tensorflow's tutorials are top notch. Since I can also use Tensorflow on my own hardware and anywhere else I really love better docs and MOOCs in general. What I really want to do is understand enough Tensorflow to reproduce other people's experiments in their papers on github and I think this would be one of the best ways to do this. Of course, this may eat into a bunch of companies that have paid programs for ML but its Google's prerogative to make ML cheaper and easier to deploy and learn so I am all for that.
