You do realize that they're entitled to using fabricated figures as examples in order to better convey their point, correct? It's doubtful that there's a set "low" for energy costs such as the one stated; they just gave you an example to better illustrate their point.
That being said, it's been stated MULTIPLE times that OOO has very little/no input on the user-driven market aside from whatever the users decide to do after an update with their crowns or energy. The only sway they have is based on the types of updates that are released, and I doubt that "crashing" an energy market of any kind is going to decide what kinds of updates they put out in the future.
That being said, just to be a troll about it, let's play the devil's advocate here for a moment. Let's say someone like... well, me, decided to go buy up all the energy you were selling for next to nothing. I've got enough crowns saved up to where I can make at least part of this statement a reality. Not to mention the simple fact that you're forgetting that while energy is an arguably limited supply (at least in CE form), that crowns gained from tier diving are only as limited as the amount of energy used to gain them. Meaning someone can easily go on a mist energy dive, gain 1000 to 2000 crowns (whatever the price may be), and buy your limited resource of CE out using a renewable resource of ME, thus making your plan arguably a failure in every respect.
In short, your plan's not going to work for three reasons - misunderstanding of the market system (OOO has no direct manipulation of the market system aside from updates, and that's hardly considered a "direct manipulation of prices" as much as it is "appeal to the users who in turn change the tide of the market), lack of promotion to a wide area of players (it's safe to assume that the forums don't form a large amount of the userbase to begin with), and lack of understanding in basic economics in general (if supply is high and demand is high, prices will remain stable, it's when supply is high and demand is low that prices drop, and energy is always in demand, regardless of what you might think).
Let me know when you plan to "crash" it, I'll make sure to buy up as much as I can for the 5 minutes or so its at such a low price.
