The same poster repeats the Coinkite sentence, "The hacker could have done the right thing and responsibly disclosed", quote-posting his own earlier post of it seven hours later and this time attaching an image: a person wearing a Coinkite T-shirt printed with a COLDCARD and the words "I responsibly disclosed a Coldcard Vulnerability and all I got was this lousy T-Shirt!". The point is the retort, that the vendor's stated preference for responsible disclosure is answered by how it is said to have rewarded a past researcher, which connects to the merchandise claim in vladcostea-disclosure-history already in the register. Held because it is the sharpest captured form of that argument and because it shows the vendor's sentence hardening into a slogan within a day. Whether the shirt is a genuine Coinkite item, and whether any researcher received one in the circumstances the retort implies, is not established by this archive.

This post is registered as evidence and has a locally held capture. The original remains the canonical publication.
