I don't see how it's "troll-ish". To an end-user, the fact that WP8 uses the same kernel as Windows 8 means nothing. It might be an exaggeration but given the rest of the comment was relatively constructive, it's forgivable.
On the UI side, his major complaint is about information density (a common complaint about WP7/WP8 apps). That's definitely valid; and I say that having used WP8 (briefly) and not minding it so much (a feeling that could change over extended use).
As an iOS user, Windows Phone's aesthetics are definitely appealing (and the Twitterrific app on iOS channels some of WP8, I feel), but the lack of stand-out apps and games is the real killer. No Reeder, no Instapaper, no Instagram or VSCO cam, no Byword, Sword & Swocery, etc.
