Well then they'd be in breech of copyright, OSM data is Creative Commons licenced (CC-BY-SA) (It's due to be relicenced soon). There are well understood, legal, avenues to explore when companies breech copyright. We don't need to resort to name calling.
Wrong discussion. This is the one about the blog, not OSM's response.
Not to belabor the point, but Apple explicitly refused to give credit the moment they published the App.
Despite whatever insinuations you might be making, of course OSM is pursuing their goals - goals which are utterly legitimate, legal, above board, intended to promote the general welfare and not for private profit or stockholder value.
What Apple did is shameful but I think what OSM is doing is most likely to promote their goals. Let others write the outraged articles.
