I think they were trying to deescalate, and your reply is more aggressive than necessary. FWIW, "disingenuous" carries the connotation of intentional deception, i. e. making an argument in bad faith, because one knows that it's wrong. In this case, I can understand where the defence of Android's implementation is coming from: the original description amounted to "plain text in the filesystem, but the name ends in .mp3 so nobody will find it", whereas the reality seems to be a slightly less elegant solution that can probably be subverted by a dedicated nation-state, but is unlikely to ever make a difference in most people's lives.
