The money was supplied by Jump Crypto, a fact I found out about just 5 minutes ago. At least we know where it is coming from but I still have the same questions. This ETH isn't an investment. They casually gave away $320M in Ethereum that they will never get back.

Who makes a decision like that in a split second?

Also, all of these protocols claim to be decentralized but have a very centralized approach when it comes to sharing information with their userbase.
