All of this is so sad! 
My take on this is that many of the respondents on this thread earnestly want to help. However they find it difficult to do so because they’re invariably wearing a business rather than an IT hat. Unfortunately their hat is deemed less important for the longevity of the project.
I also come from a business angle, although I can help myself ( and others : [Tutorial] Using cURL for REST and RPC API calls ) with some tech related stuff, I nevertheless find it very dis-enfranchising to read how our desire to assist is being trampled upon.
Just imagine the magnitude of the force behind ERPNext if we can somehow unite both user communities. Just image the dominance this product can have world-wide. Technically it is very well constructed, but business wise it now needs the input of business users to polish it to become that pervasive solution all of us are yearning for. The one and only obvious choice for an ERP system.
Just imagine a few years from now, when we read this post again, how we’ll silently smile, knowing we did manage to overcome this division and made ERPNext the de facto best ERP system in the world.
Just imagine how easy it actually is to unite us all.
