I really don’t like this. Could I see the NDA somehow? If the wording equally forbids sharing good and bad stuff about Leverage, then I’m much less bothered by this. Likewise if the wording forbids going into certain details, but lets former staff criticize Leverage at a sufficient level of abstraction.
Interestingly my comment further down that asks for details about the information sharing practices has very little upvotes ( https://www.lesswrong.com/posts/Kz9zMgWB5C27Pmdkh/common-knowledge-about-leverage-research-1-0?commentId=qqAFyqZrfAdHsuBz4)
It seems like most people reading this thread are more interested in upvoting judgements then in requests for information.
