I know we differ significant when it comes to using centrazlied/decentralized exchanges and our approach to KYC, but even when only discussing centralized exchanges I completely disagree with this statement. Coinbase admitted they were selling customer data to third parties. Coinbase bought out Hacking Team, which manufactured and sold surveillance software to human rights abusers. Coinbase have partnered up with the IRS, the DEA, and the Secret Service. There isn't an entity in cryptocurrency I would trust less than Coinbase with my data.
I don't mean privacy from The Man, that's a given. I'm talking more about it being lifted by hacking types.
Some no mark fake volume exchange could be doing anything with what you send them. At least Coinbase are only using it to allow governments to imprison your mind and soul.
