Somebody in the position to know, eh? "Elsewhere," you say?
Josh Sawyer was shown the PoE portrait of him that I commissioned Jaceface to paint by the goons at Something Awful, where it made the rounds. Obsidian almost certainly showed it around the office too, and the meaning of the imagery is pretty clear.
My intended message spread through virtue of Jaceface's talent, but here's the reality: At the end of the day, no one cares. Obsidian's own relevance to the larger industry is marginal to begin with. Keep in mind that this is a studio whose most successful titles are based on and/or subordinate to other companies' IPs. The staff may well have read Roxor's review and thought "He made some good points," and then they probably went to lunch at Quizno's and forgot about it because we, as a target audience, don't really matter.
The "fan murals" I created in Photoshop for Underrail's release were posted by Styg on the game's website. No one really gives a damn about that either, nor should they. We're specialized hobbyists here having our little fun.
The Codex does occasionally blip radars outside of our little bubble, yes. This doesn't really translate into actual relevance, though.
