Look, this blog post contains good advice for academics. You seem to be overreacting quite severely. The truth is that the utopia where anyone can work on interesting problems is long gone or rather never really existed (http://amapress.gen.cam.ac.uk/?p=1537). Academia produces a massive oversupply of academics, and there isn't the capacity to fund them all. Funding bodies in general are talking more and more about 'impact' as a deliverable. The original post is just trying to say don't ruin your chances to get funding with faulty thinking about industry applications.

You can argue, quite rightly perhaps, that focusing on impact/industry applications is a bad idea, and that we will miss out on important epochal discoveries, but that is a problem with society, not the author of the blog post.
