That seems like a good question to pose about the person who is leading up the “Department” of Government Efficiency (DOGE).

They have massive market share. First-mover advantage is quite a powerful thing. The barrier to entry for a new competitor in either eBay’s or PayPal’s marketplace is huge.
Also, this is not a new thing. eBay has been increasingly putting the squeeze on sellers since the early 2000s. It’s gotten steadily worse over that time period. And the enshittification that produces revenue for eBay also acts as a deterrent for any potential buyers, since search isn’t usable. eBay used to enforce rules against headline spamming, excessive shipping costs and other sharp practices by sellers that degrade the user experience, but don’t seem to bother anymore. At the same time, legit sellers get screwed in myriad ways.
