EthHub co-founder sassal.eth refuted the above remarks, saying: “I really don’t want an industry leader like Zooko to say this kind of crap, and since he banned replying to this tweet, I have to correct this mistake here information.

Tornado Cash was never “closed”, it is still running today, and a majority of validators are still proposing blocks containing Tornado Cash transactions.
