Empery Digital Responds to Major Shareholder Proposal: Will Not Liquidate Bitcoin Assets
March 3 — Empery Digital Inc., a Bitcoin treasury firm, pushed back against certain shareholders’ demands to liquidate its Bitcoin assets on Wednesday, stating it will not sell its Bitcoin reserves and deeming the proposed action not in the best interests of all shareholders.
The company noted in a statement that its board and management have thoroughly reviewed the proposals, concluding the mathematical logic behind immediately liquidating all Bitcoin holdings is invalid and would deprive shareholders of potential gains from future Bitcoin price increases.

Anthropic's Controversial US Department of Defense Contract: Altman Reaffirms Military Principles, ChatGPT Uninstallation Rate Surges
**March 3 Update: AI-Government Collaboration Debates Intensify**
Controversy over Anthropic’s partnership with the U.S. Department of Defense (DoD) is escalating. OpenAI CEO Sam Altman posted snippets of an internal email on social media outlining the company’s core principles for working with the DoD: *“We will not build autonomous weapons without human oversight.”* The move is widely seen as a public contrast amid the Anthropic debate.
Tech commentator Packy McCormick, citing Ben Thompson, highlighted the so-called “Hype Tax”: *“If you don’t want the government to treat your tech like a nuclear weapon, don’t frame it as one yourself.”* The commentary critiques some AI firms for overhyping technological disruption, noting this framing could backfire in policy and regulation.
