But you're a developer. A sales manager (for example) couldn't care less about your objections.

He wants his pivot tables, KPIs and Solver and some macros. He wants point-and-click ETL. If it's a department/cross-department model, do it in SQL Server, or whatever else you use. You can use your IT kung-fu there. This is about what libre office lacks. Excel has power and flexibility and remains easy to use for non-programmers.
