But business software is super boring, takes forever to please the customer who typically is difficult to deal with, wants the UI buttons in specific places, the data entry form to be in a specific format, etc etc. Why would anyone want to work on that? Open Source works primarily because the software you work on, you're personally invested in it, and you care about it, and its about scratching an itch. When you tell people to 'follow their passion', nobody is going to want to clean the toilets and mop the floors.
