Anthropic Long-Term Benefit Trust — key-event: Jason Matheny departs as trustee

NoteThe source directly confirms the claim. The footnote at the end of the article explicitly states that Jason Matheny stepped down from the Trust in December 2023 (matching the claimed 'as of 2023-12') and provides the reason: to preempt conflicts of interest with RAND Corporation's policy-related initiatives (matching the additional context about 'conflicts with RAND policy work'). The subject of the source (Anthropic's LTBT) matches the claim's subject exactly.
