You can, of course, be critical of anything they do, because "Frontier bad"; but as I understand it, those audio puzzles with hidden images have been
very popular and somewhat highly praised in the past, and I have read the occasional "bring back those hidden message thingies". Damned if they do, damned if they don't. And for the record, I was very giddy to find this message, because I knew those puzzles only from fairytales from "way back when". I've been playing for four years now, and this is the first reoccurance of an audio image puzzle.
And a good one too, because, as
@Jmanis pointed out, there hasn't been revealed anything in this hidden message; you don't miss out if you don't find it, and if you do, all that happened so far is that the audio logs get even creepier.
