Last week, a number of companies, including Apple, IBM, Disney, Paramount Global, refused to advertise in X. This happened after it became known that ads for Apple and others began to appear next to posts with radical conspiracy theories and anti-Semitic appeals.

After that, Elon Musk carried out an information attack on large advertisers and the Media Matters group, which monitors the media.

Musk wrote Friday in X: “Court opens Monday, X Corp will file a fusion lawsuit against Media Matters and EVERYONE who colluded in this fraudulent attack on our company.”

In subsequent tweets, he added, “Their board, their donors, their dark money network, all of them…” and “the discovery and testimony will be interesting to see.”

Earlier, Media Matters also found that many companies’ ads could be seen alongside extremist and anti-Semitic posts. These companies included Apple, IBM, and Oracle, among others.
