> From the manufacturer, in house drivers is a HUGE cost savings, and removes your product from being perceived as a pure commodity.

If this would always be the case then almost all brands would do it. Only very small brands would have to wait until they become a bit bigger.

I am pretty sure making your own drivers could be a huge cost instead.
