It seems Wasabi software doesn't prevent users from merging the outputs that came from the same CoinJoin round, which essentially destroys all privacy gained as a result of a complex transaction.
There is also some issues currently with Tor that is under DDoS attack (I noticed slow loading times for my other wallets that use Tor) and this could also have negative effect on Wasabi 2.0 coinjoins.
Tor is also updated to 4.7.8 few days ago with major bugfixes:
https://gitweb.torproject.org/tor.git/plain/ChangeLog?h=tor-0.4.7.8The output of this transaction (according to KYCP) belongs to OKEX exchange, which means that all these inputs were sent directly to someone's exchange account and, therefore, can be linked to a particular identity.
Not necessarily, because I believe that OKEX exchange has no-kyc tiers and that would not automatically connect those addresses with customer identity, unless OKEX stuff demands it from him.
