Based on firsthand accounts of what Wallace suffered, this seems like an irresponsible account of his death to run unqualified --- though it fits with the rest of the one-note cynicism that runs through the article.
Wallace had a life-long struggle with clinical depression, and was hospitalized in his 20s. He was for years on a regimen of Nardil, a third-line medication for treatment-resistant depression. The major depressive episode that preceded his suicide appears to have been triggered by an effort to wean himself off the drug.
Mental illness is a real thing. Just as Steve Jobs cancer didn't make him a martyr to tech and Keith Haring's AIDS didn't make him a martyr to art, succumbing to clinical depression doesn't make Wallace "Kurt Cobain" or his death a "career move".
The whole article bugs me, with its shrill hipsterism, a literary version of Courtney Love's "REM's important work was done before they signed to IRS". On a limb: I think the article itself is doing the same thing it accuses the world of doing by rewriting any sincerity out of the stuff people like about Wallace's writing. This despite the fact that in addition to being by all accounts kind of a dick, Wallace was also apparently just a "treacly" kind of dude, as the essays he wrote in Normal, IL indicate.
