Maybe the cooling of the tech sector in the US/EU has something to do with it. Tech in Asia seems to be fine.

Twitter's ad revenue plunged due to mismanagement and current economic conditions. Lest we forget, when Musk took over, the workforce dropped by 80%, which meant, first of all, that a lot of advertisers lost over night their contacts at Twitter. And while moderation may have stayed in place, Elon Musk also started unblocking far-right accounts and he can't keep his mouth shut.

I can't speak for Asia, but multinational brands (like Coca-Cola) are actively avoiding controversy and you don't need activists for such an effect.

Are you saying the only plausible explanation is, "the Jews?"
