Since the article is already based on a leak (or something that is presented as one), one would expect that if this was the case, there would at least be an anonymous source claiming so.
Given that all the article is mentioning is "they're selling blockchain analysis software", it's very plausible that that's what they're selling. When the feds want specific info on a specific address/account, they're going to get a subpoena and get KYC data and logs anyways.
