Well, their point has much more substance than your "this is ad hominem" slur since the blog author didn't disclose that his opinion piece is directly tied to the business model of his startup (and therefore wants to sell you the solution so they are clearly biased). Some people may therefore feel deceived.

What I'm saying about the "ideas" is that they are entirely based on a delusion which is stated as a fact, but only because the author has a strong incentive to believe the delusion.
