I wouldn't say that necessarily...
And if it was intended as a troll, then it's not exactly a "succesful" one in terms of being "so over the top" that anyone giving a moment to think about it would figure it out.
Cash Shops are an increasing element in many MMOS these days, other developers - F2P and P2P alike - are implementing them... even if they've said in the past they never would in existing games (ie. Smedley with EQ2).
Also, SE has been asked about their take on Cash Shops in the past and, as I recall, the answer they gave was basically "if enough people want such a thing we'll consider it".
So.. if it was a troll attempt, then they failed in having not picked a very troll-worthy topic.
The subject of Cash Shops is a very valid and very current one in the genre.
