Well if you want a buyer's perspective, it's because eBay has become a waste of time which adds no value and gets in the way:
1) Search for something common and you get page after page of the same item with tiny differences in price. Where is AI when you need it? Waste of time.
2) Much of the above turns out to be cheap tat anyway, hardly even worth the bother of returning.
3) Sellers of the above still get high 90s % feedback, therefore ratings are worthless.
4) UK only default search option? No, I have to select this for each new search. Waste of time.
5) No returns process after 30 days. The 30 day thing was only supposed to be extra protection for online buyers. Consumer Rights go way beyond 30 days: 6 months if the item was a fake, and a reasonable life before it wears out or breaks down.
6) Ever-changing rules, policies and processes. Waste of time.
7) Sellers should only be allowed to leave feedback after buyers do, it's just silly to give instant feedback. I don't need to be told how delighted the buyer is that my payment didn't bounce! Just another way to generate high but worthless ratings.
I might still use eBay if I want something obscure or collectable. Otherwise I much prefer to deal with business sellers directly. Mostly for reason (5). The exception to this is Amazon who are usually helpful in resolving issues after 30 days, even with 3rd party sellers, because they value my custom.
