I used to work for a Japanese multinational making networking gear. Excel was part of the mandated SOE, and was used for everything (even unit testing frameworks in VBscript), so this would be a no brainer for their environment. The engineers would have difficulty getting this purchase through as it is too cheap for the enterprise version... In the accountant brain, cheap == a toy for a number of companies.

I think the logic is like "they can't possibly support this product at this price point, we would rather depend on something which may be inferior but well-supported".

Support is such a crucial point in enterprise software. The reason why they pay big bucks is they have someone to call when something goes wrong
