No they are saying they don't need a decentralized public blockchain because they can't control it which is well the whole point of it.
They're giving funny excuses like:
Hence, proof-of-work-based blockchains like bitcoin offer no way to predict their future security level, or settlement, since it is directly proportional to the tokens future value, which is not knowable.
which is an interesting point about bitcoin, but is also laughable because one can say the same of the US dollar. It's a token whose future value is not knowable. We'd like to believe it's a stable store of value, but the Federal Reserve and US Treasury are the counterfeiters of the global reserve currency. They can devalue at any time.
