I'll suggest that the other stuff causes enterprise software to be of low quality.

Not all enterprise software sucks, although much of it does. Often there are non-sucky options in the space, but they have less market share in no small part due to that other stuff. On the client side of things, if you can fix the politics you can generally fix the suck but that means as a supplier your success will be determined (in part) by how well you help the client address the politics and "other stuff". Sucky enterprise software exists (in part) because many suppliers have found that there is greater return on focusing resources on the other stuff than on focusing resources on improving the software.
