Large rival companies say Amazon restricts how competing products, like smart speakers and video doorbells, can be advertised, giving Amazon's devices an edge
Wall Street Journal
Context & Ripple Effects
This report lands at the start of a documented arc: rivals allege Amazon limits how competing smart speakers and video doorbells are advertised on its own surfaces, tilting discovery toward first-party hardware. The Wall Street Journal's later sourcing on how Amazon compels vendors across markets, including threats of punitive action spanning unrelated businesses, and its December investigation into campaigns to steamroll rivals and partners, extended the same leverage story from advertising terms to marketplace conduct broadly.
The smart-home angle then drew direct political fire: at a Senate antitrust hearing, Amazon and Google defended their smart home device businesses to critics in both parties, and a subsequent investigation found Amazon placing its own brands above better-rated competitors despite telling Congress otherwise.
First-order effects
Device makers competing with Echo and Ring lose advertising visibility exactly where purchase intent concentrates — on Amazon's own properties — while Amazon's first-party hardware gets the default placement edge.
Rivals' ad budgets effectively become constrained instruments: they can buy less reach than their shelf position implies, distorting how shoppers compare products in the category.
Second-order effects
Competing device makers have every incentive to take their grievance to Washington rather than to Amazon's negotiation table — a dynamic that surfaced months later when smart home businesses were put before a Senate antitrust hearing.
As reporting connects advertising restrictions to broader cross-market pressure tactics, Amazon faces the risk that individual vendor complaints harden into a single antitrust narrative covering both its retail and devices businesses.
Third-order effects
If the documented pattern holds — ad restrictions, cross-market coercion, and self-preferencing of first-party brands — regulation aimed at platform self-preferencing becomes the structural endpoint, forcing gatekeepers to choose between operating the marketplace and competing inside it.
Hardware rivals may permanently reweight demand generation toward channels Amazon does not control, fragmenting smart-home distribution and raising customer-acquisition costs across the category.
The trend: Platform gatekeepers that sell advertising while competing on their own shelves are moving from private disputes with vendors into the crosshairs of structural antitrust action.
So like, this is just our national tone now? Fun. Amazon spokesman Drew Herdener: “Walmart refuses to sell [Amazon brands] Kindle, Fire TV, and Echo. Shocker. In the Journal's next story they will uncover gambling in Las Vegas."' https://www.wsj.com/...
You are an Amazon family, an Apple family, or a Google family. I wrote about this in my latest book The Big Nine, and we're seeing the scenarios play out in the real world now. Don't say I didn't warn you. https://twitter.com/...
Amazon is limiting the ability of some competitors to promote their rival smart speakers, video doorbells and other devices on its dominant e-commerce platform, Amazon employees and executives at rival companies and advertising firms tell the WSJ https://www.wsj.com/...
“Roku and Apple ... have to worry about rivals buying search terms even when the searches are for exact brand names. For instance, a search for ‘Apple TV,’ could return a sponsored result from Amazon for Fire TV. A search for ‘Fire TV,’ will not return a rival product, though.”
NEW investigation: Why can't some Amazon competitors buy good placement for their devices in Amazon's search results? Because Amazon won't let them. https://www.wsj.com/...
Amazon has prevented its biggest device rivals from buying sponsored product advertisements using Amazon keywords, even though it allows smaller rivals to buy these important keywords. Story with @patiencehaggin @shaneshifflett https://www.wsj.com/...
Amazon PR flack to WSJ: “News flash: retailers promote their own products and often don't sell products of competitors.... Walmart refuses to sell Kindle, Fire TV, and Echo. Shocker. In the Journal's next story they will uncover gambling in Las Vegas.” https://www.wsj.com/...
