This is not true. From the article:
"I'm surprised — that's strange," a former senior Amazon advertising manager told Insider, referring to Apple's clean product and search result pages. "I wouldn't have the discretion to offer something like that."
At least half a dozen salespeople on Amazon's advertising team told Insider that they were not able to extend this Apple-style special treatment to their clients. Large advertisers on Amazon constantly ask for this type of exclusivity, but the company usually denies those requests because it wants a diverse set of search results and ads, one of the people said. To create Apple's clean product and search pages, multiple teams at the most senior levels at Amazon would have had to get involved, this person added.
"We balk at companies that want to buy all the ad slots," this person said. "I have never seen, nor do I have the control to give, that type of right."
