Previously their business model was simply to create a fast-lane into Amazon ordering (e.g. "Alexa order me some toilet paper"), but if what the article says is true they're going to ruin normal searching by only giving you product results (Q: "alexa how do I remove a wine stain?" A: "buy Dr. Bubbles Super cleaner"). If Echo is going to give me bad results for questions I'd just stop using it for that.
I'll use whatever personal assistant gives me the highest quality results. If your business model inherently degrades the quality, then your business model is self-destructive.
