"All" sounds like marketing to me; if the bleeding edge AI firms knew how to do such a thing with such reliably, they'd do it themselves to prevent models from committing felonies while under test. Improving false positives scores at the expense of false negatives, that's much more likely. Propaganda can still move things when it's reduced frequency.

And propaganda has the added twist that, when done right, the person observing it nods along and changes their mind. "Why yes," they think, "Chinese politicians are clearly much wiser than ours; our politicians made all those mistakes I can easily recall, gosh those were the worst". Or perhaps "Yeah! Why should American blood be spilled to defend a small island on the other side of an ocean!" (not that it matters if the ocean is Atlantic or Pacific, nor if the island is Taiwan or Great Britain).
