CCP has stated in the past that the money generated by Dust doesn't actually even come close to covering the cost of development. It is the Eve players who are paying to produce this game so you can think about Aurum as paying devs all you want, I am sure some of the cash needed to keep the game going comes from Dust but the vast majority of it does not.

Having deals on Aurum items doesn't actually increase the rate at which players spend cash on the game, rather it allows them to buy more of the same assets they would purchase anyways. This in fact reduces their need to inject cash into the game and rather than increasing the cash flow for CCP more likely reduces it.

Aurum can be effectively calculated as isk in relation to the weapon values. X Proto weapon costs Y isk, X aurum proto weapon costs X2 aurum, Aurum cost then is calculate like this: Y/X2=Z isk

I don't think you understand what I'm saying. Yes, DUST was developed with other money than Aurum stuff. (Possibly some EVE revenue, and very likely outside investors.) But since CCP's a business, and they make things under the intention of turning a profit, the long term plan is obviously that DUST's own income, from Aurum, needs to eventually make back the money they invested in developing the game. And turn a profit on top of that.

I'm not going to go back and rewatch the entire YouTube history of CCP because someone makes an unsubstantiated claim on a forum post. If you want to claim it as a fact, you should be able to reference it.
