Apple is reconsidering advertising on X after many nonprofits and civil rights groups reported that antisemitic posts increased since Musk's takeover.
CEO Tim Cook said that there is "no place for it" on any platform, even though X may be an important space for discussion and debate.
Cook's remarks follow Musk's upcoming meeting with Israeli Prime Minister Benjamin Netanyahu.
In the meeting, they plan to discuss artificial intelligence amidst concerns about antisemitism on X.
After repeatedly denying these allegations, Musk threatened to sue the civil rights group, Anti-Defamation League.
Must would sue for a loss of 60% of advertising revenue due to the accusations.
Musk also sued the Center for Countering Digital Hate for publishing a report claiming failure of action against provocative content by X Premium users.
