Today, executives from both Amazon and the server manufacturer, Super Micro, are calling for the retraction of a Bloomberg report published earlier this month. The report alleged that these chips were able to compromise the computer networks of as many as 30 companies, including networks belonging to Amazon.

Last week, Apple CEO Tim Cook called for Bloomberg to retract a report claiming that Chinese spies smuggled malicious microchips into a company server. In an unprecedented move, Cook sat down for an interview with BuzzFeed News last week in order to address the allegations proposed in the Bloomberg report. Cook said, “This did not happen. There’s no truth to this,” eventually calling for the publication to retract the story which he said Apple had been denying in conversations with reporters for months.

The other two companies named in the story, Amazon and Super Micro, decided to follow in Apple’s footsteps today, offering their own statements condemning the allegations.

“@tim_cook is right. Bloomberg story is wrong about Amazon, too,” Amazon Web Services executive Andy Jassy said in a tweet earlier today.

@tim_cook is right. Bloomberg story is wrong about Amazon, too. They offered no proof, story kept changing, and showed no interest in our answers unless we could validate their theories. Reporters got played or took liberties. Bloomberg should retract. https://t.co/RZzuUt9fBM — Andy Jassy (@ajassy) October 22, 2018

On Monday, Super Micro said that the company would continue to investigate the claims and review its motherboards in search of any hardware manipulations. Just hours after, Super Micro CEO Charles Liang said, “Bloomberg should act responsibly and retract its unsupported allegations.”

The report cites 17 unnamed sources and no compromised hardware has surfaced in the weeks since publication. The report garnered nearly instant criticism when it was published earlier this month from cybersecurity experts who were unconvinced by the available evidence.

Officials from the Department of Homeland Security, National Security Agency, and the UK’s top cybersecurity agency have also come forward, saying that they have yet to see any evidence corroborating Bloomberg’s claims.
