Except they don't say in the post that they ship mostly Kindles, from what I can tell. Kobo units are available in more markets than Kindles, and they don't disclose if they bought the Kindle and borrowed the Glo, or vice-versa. They're supposed to explicitly disclose any connections, so if a review seems biased, it's obvious why.
In this case, they don't. It's almost like they don't want Amazon to jump on them for reselling units outside of designated markets, by glossing over the faults of the PW.
