I don't consider the majority of drop-shippers to be economically productive businesses: they are charging a premium because their customers don't know that they can buy the exact same SKUs from AliExpress. Customers of these business often pay 2-5x mark up on items based on marketing and lack of information, because these business are effectively just pure marketing plays. There are certainly good small businesses, both on Shopify and elsewhere, and some would be hurt to some small degree by this change. I'm simply arguing that the majority of business which would go broke without the use of the FB ad system tracking panopticon are not the sort of small business which are societally useful or that we should mourn their loss. "Small businesses going bankrupt" typically is thought of a negative thing, but there are flavors of small businesses where it is really a net societal good.
