Mind boggling.
It is indeed mind boggling. There's absolutely no excuse for any crypto exchange to trust third-party chain analysis organizations. If these exchanges love bitcoin and crypto in general, they have inherent motivation to limit the power of chain analysis organizations. Their financial future is dependent on keeping bitcoin fungible.
Chain analysis isn't here to help bitcoin, it's rather obvious the intent is the opposite. Having governments and regulatory bodies oversee chain analysis isn't the solution either. Governments are threatened by bitcoin; their power is largely determined by how well they can control the flow of wealth within their jurisdictions. The less control they have over money, the less power they can enforce. How do we know that it isn't the FBI, CIA, NSA, or the SEC behind these taint proclamations? We do know that they stand to benefit from hurting the fungibility of bitcoin.
After all, Bitcoin is here to set us free from the heavy chains of our current monetary system. We are a community of people who supposedly and theoretically want just that, if we exclude the speculative investors. I do not mind Bitcoin sitting at $20,000 for the next 20 years. I just want it to offer me the same freedom it did so far.
That's exactly the threat to their authority they're trying to avoid. Throughout history the authoritarians have struggled to ensure their authority isn't under threat. Bitcoin is causing them to shake in their boots.
