Vitalik responded to community questions regarding why the Ethereum Foundation does not stake all the ETH it holds, like the Nobel Foundation, and only use income to pay for costs. Why not consider market sentiment and listen to everyone's voice, and insist on regularly selling ETH? You have always claimed that Ethereum's POS is very secure, why not stake ETH yourself? Do you lack confidence in POS? Vitalik responded that one internal reason is that we do not want to be forced to make an "official choice" when a controversial hard fork occurs. The idea under consideration is to provide some grants in the form of "you can mortgage our ETH, and you can choose how to mortgage it, as long as it is ethical and maintains an advantage." Another way to solve this problem is to decentralize legitimacy and resources to more places, so that multiple organizations are seen as credible representatives of Ethereum in people's eyes. In this regard, our situation is much better than two years ago.
