I think US based folks perhaps aren't aware of what Musk has been doing in Europe politically. Specifically promoting - appearing at conferences, applying political pressure as well as public statements etc - actual fascists. Not right wing controversial figures etc, but literal authoritarian, anti-migrant, anti-EU, anti-democracy fascists. Not to be glib but if this was Mussolini-AI, or Pinochet-AI or what have you, the reaction would be the same.
If Musk succeeds in his attempts to bring fascism to Europe and breakup the EU, the humanitarian results (ie.: a land war in Europe), will be far worse even than the tens of thousands of deaths attributed to his dismantlement of USAID.
