I see this as a positive for Shopify. We work very closely with the platform, and over the years I have only seen a handful of direct-from-Chinese dropshipping sites that actually produce any revenue. Sure there are a lot of accounts that are opening with the hopes of a get-rich-quick scheme with low cost and risk.
I am certain that it is the legitimate businesses that are behind Shopify's success, and this will help with their reputation and give them a chance to focus their marketing on the right customers.
