The removal requests ask the search engine to take down links to t-shirts and merch under the justification that the products in question violate copyright law because they incorporate memes and other content that the actual, verified Musk has posted on his Twitter account or elsewhere.
Almost all of the “Elon Musk” takedown requests begin with the same description: “The following websites have stolen my copyright and they have no right to sell them, please remove the following links from search results.” From there, the complaints include a primary source link intended to demonstrate ownership—usually one of the Tesla CEO’s tweets, and usually a tweet of a meme image—and then provide a long list of sites selling merch that incorporates that particular meme.
