Overall totally agree with the insights. The part where I wouldn't think about it differently per say but where I would describe it different is about the pricing issue. You have to figure out how much value you create and try to capture as much value as you can. I think you can approximate the value that is created in B2B situations albeit very roughly and not in an exact manner. Pricing wrong is always bad but I agree that how much it cost someone to make something is irrelevant to what price you should charge and maybe you will get people to realize that with your comment "charge a lot". If you increase price but quantity decreases such that profitability is reduced not ideal. Also it would also depend on if there were same or cross side network effects for your product (I.e more users equals more value for your two sides network)
