I can see zero difference in the information density between the existing non-responsive design of that page [0], and the beta version of the responsive design [1].

While your point that mobile first design inevitably causes a lack of information density at desktop resolutions has some merit, it does not apply in this case.

They have been using those blogs to test the new layout.

If you went there over the last few months you'd be asked to give feedback on the new design.
