I wouldn't say they are artificially creating the demand. They artificatially create capacity to make a purchase by enabling their customers to pay with ownership of their business rather than with money. It's just an alternative financing scheme.
> They artificatially create capacity to make a purchase
If the company did not intend to purchase anything but Nvidia used the investment to "incentivize" a purchase then this is artificially creating demand where there used to be none. It's very different from Nvidia allowing a company to purchase Nvidia products that they already wanted to purchase but pay with stock.
