That's what the post is complaining about, but the problem is quite deeper. The KYC bit is actually ok IMO -- you're giving your identity to places that likely already have it.

What this kind of article should be about is the same thing that VPN is about. privacy.com actually removes privacy. Now, instead of VISA being the only aggregator of your purchase data, privacy.com is also. Either way, the merchant and VISA know your purchase history. Now, so does "privacy".com.

If you want to hide something from your bill so that someone else in your household doesn't see it, then ok. If you want to hide your address and name from a merchant (say for a digital downlaod) then ok. If you actually want more privacy, privacy.com is the opposite of what you want.
