I feel like that commenter was a little harsh with that statement - I will say however that it has caught some flak as a source of truth. There are quite a few standards (principally, original jazz compositions by jazz musicians that have now become "standards", this probably isn't as much a problem for true "Great American Songbook" standards since those were always notated), that were transcribed incorrectly in original versions of real/fake books. To the point that many younger generation players are playing incorrect heads and/or changes to tunes since they learn it from the book rather than by ear. Not even that, but often they are just straight wrong, or dumbed down versions of the changes.

Actually… this is true. Fair enough.
