Browsers can verify for themselves that an article is really from the NYT; that’s the whole point of digital signatures
Editing can be addressed by wrapping signed original signatures with the signature of the editor.
CopyCop can not obtain a camera that signs with “https://www.nikon.com/″ unless the private key of Nikon has leaked (in which case it can be revoked by Nikon and replaced with a new one—this means old signatures can’t be trusted). This is the whole point of digital signatures.
There’s no need to maintain a chain of custody. The signatures themselves do that. All that’s needed is a functional Public Key Infrastructure.
That all said, of course this remains “an obvious partial solution”.
