Why did Mark Ruffalo criticize Paramount over antisemitism accusations?

Ruffalo hit back after Paramount accused him of invoking "antisemitic tropes" over his criticism of the Ellison family's proposed Paramount-Warner Bros Discovery merger, specifically his objections to the studio's financial ties to Israel via Oracle, which is backing the deal [1, 2, 4]. He called the accusation "appalling and fundamentally dishonest", arguing that criticising Israel's prime minister, military technology contracts and the executives supplying them is not the same as antisemitism [2].
