Strange day but not entirely surprising. I understand theymos gotta do what he gotta do to first and foremost make sure the forum doesn't get taken down... that would be a real blow to the history of Bitcoin. The one thing I'm not quite sure I understand is the KYC part. There are several exchanges that still do not require KYC, even if they aren't allowed to service U.S.-based customers.
Isn't Bitcointalk decentralized forum where everyone has freedom to talk on any subject even against any government?
No, Bitcointalk has never been decentralized. Theymos has done just about as good a job as possible keeping it "free", however.
