Actor Mark Ruffalo has been accused of antisemitism after publicly criticising the family behind a major US media merger deal, noting their ties to technology sold to Israel for use in its military campaign in Gaza and its treatment of Palestinians in the West Bank. Supporters of Ruffalo argue the backlash conflates legitimate criticism of corporate power and alleged complicity in human rights abuses with ethnic prejudice. The controversy has reignited broader debate about who controls American media and whether accusations of antisemitism are being used to deflect scrutiny of those ownership structures.
