Not silence. Sequoia posted a letter declaring that their FTX investment is $0 and that this is not a notable fraction of their portfolio. FTX may have been a theoretically sound investment for Sequoia because many venture investments are marked to $0, and FTX got to huge-or-zero much faster than any other investment. A company that slowly goes to $0 is equally bad but worse for time-value.
What hurts my brain is that theoretically this investment strategy is sound, but the implementation of it looks like: FTX. It's horrific. It's like total war logic. Logically it works, probabilistically it's reasonable, living it is grotesque and insane.
