The Gruen transfer seems to make use of confusion or disorientation upon entering a new physical space. On the other hand, the phenomena described here with data search implementations (e.g. a feed) intentionally returning things that were not asked for does not rely on user confusion. The user already made a perfectly legible request by performing the query (e.g. opening the feed). Ignoring or misconstruing this request is gaslighting. The site tries to pretend that the user asked for something different than they actually did and to sneak this subterfuge past them. It's rampantly unethical. The purported justification I've heard is that fuzzy search can find results in cases when exact matching does not, but taking the control of fuzzy vs. strict search out of the user's hands is unethical because it is motivated by the opportunity to introduce mistakes and pervert intention.
Sites like Etsy implement this dark pattern in ways intentionally intended to make CSS-based blocking of injected sponsored products difficult to block. The arms race between user agents and corporate manipulation continues, and corporate web designers will use every tool available to subject users nonconsensually to their preferred experience. This is why I consider it a net loss for users to add functionality to the "web platform". The corporation is your enemy and they're well-funded.
