I don’t have a good model for what lower B2B prices would look like when company age/growth aggression/pricing unsophistication are factored, though. I don’t take the presence of some downside for granted because projects like this can be taken by incumbents and bundled into high margin services (copyleft helps a bit here.) Would welcome data.
This model to depress prices does definitely work in B2C, but it’s not necessary to develop an open source app to get cloned to drive down prices there; it happens to everyone.
Ask the vape companies that were on Shopify for nearly a decade and Shopify kicked them off a couple months back. I bet they wish they went with open-source instead of blindly trusting a company to whom you are expendable.
