With other digital goods the distribution and operating costs have been essentially free. No business worried that much about the cost of running Microsoft Office on the PCs they already distributed to their employees. They were only concerned about the licensing costs. And Microsoft didn't worry about the cost of printing CDs or the costs of serving Office online. It wasn't zero, but again negligible compared to the cost of development and the licensing costs.

For LLMs the costs of training and inference are a very significant part of the overall costs.
