No where was it ever stated that they would have zero intervention on the WoW token. So assuming that it is completely a 'free market' is itself (in your words) a 'conspiracy theory', because there's zero proof of that being the case. It was just passed off as legitimate premium 'service' for buying gold or game time. Blizzard never stated that they'd keep hands off and let the market work itself out with zero intervention. There is no lie except the one that you seem to be telling yourself and pawning off as some commonly-held truth in this discussion. I mean, where are you even drawing the conclusion that it's a 'free market' at all?

This is the original announcement and FAQ for the WoW Token. You'll see that nothing in it pertains to it being a free trade market. The only thing comparable is simply basing the system off the Auction House transactions, but without any tangible affect on the market as a whole. There is no undercutting, there is no personal market value for token sales, there is no individual intervention on the supply or demand of tokens. The market is anything but free. It is absolutely regulated.
You can be hopeful that they are keeping out of it, but just the same you have zero proof for your own position. There's really nothing that we have here to disprove any alternative take on the situation. And the fact remains that they *do* have full control over the system they've created, including having full control over the amount of WoW tokens in circulation. If they want to remove 10,000 tokens from the market, they can do so at the press of a button, that's all within their power and their right to do so.
