For me, the key part of the linked article is: "...but MoneroV operators might obtain a significant amount of knowledge about the contents of the Monero blockchain through users giving MoneroV their private keys."
So, what I guess the author of the post is saying is that we have a MORAL responsibility to NOT help (those factions of the US - as implied above by owlcatz. Where do you find anything about the US?) who are trying to break the anonymity of Monero and that outweighs the making of some (potential) free money.
And, by logical extension, that outweighs whatever IMMORAL activities may have been paid for with Monero.
Kind of reminds me of the old comedic line, "I got mine, now you get yours."
No, sorry, but in my mind, if a valid method exists that exposes vulnerabilities in a system, in this case, Monero via a fork - using standard fork methodologies, then it MUST be followed for the development of the future. If that means that all are exposed in the past, too bad. Those who put their TRUST in such a system are fools because they didn't see this coming. It is more important to accept that this may be a problem for de-anonymizing Monero and plan for the future accordingly.
Implying that one must oppose on moral grounds is antithetical.
