I have no problem with the article having been sponsored. It was disclosed, so everyone can assign whatever weight they want to it. I personally liked it (perhaps this speaks to my own confirmation bias) and if it reaches writers who might do their own DD and pen another factual article, that would be great.

This is not a situation where a company (like Galena and others) wrote articles for authors to publish - unattributed to the company - under their own names.
