The key is to shave the yak before you're forced to.
Lots of sellers get their start on e.g. Amazon marketplace, and they find it becomes progressively more awful as they scale up.
If they make the switch to their own site on their own schedule, this is fine.
If a competitor puts in false reviews on their product and gets them banned, or their search rankings mysteriously plummet, the loss of revenue can bankrupt them before they stake their own site.
