Dropshipping can be a nightmare for an advertiser, because if their account gets algorithmically banned by the platform, they may also find that all of their products have been removed from the platform and it will take time before their accounts are reinstated. For marketers, on the other hand, this means they just lost a customer without having to get into any more of a sales pitch with an uninterested person.
On ebay and various platforms offering dropshipping services such as marketplace websites like Alibaba and Trade King had made it so anybody could be in business for themselves and profit off of "dropshipping".
Dropshipping is a dream for marketers because now they can sell products that don't cost them anything. While it may not be as much instant gratification as earning sales for items they own and ware, the income streams are steady and consistent. The downside to this approach (although some might say "the upside") is that people will short ship products all the time, sometimes with little or no warning at all, which can make revenue stream unpredictable and also cumbersome for those who created the link between designer and buyer.
