Not only unethical, but a violation of Ebay policies.
Please do a bit of research and learn what a "reserve" means in an auction.
Unbelievable.:banghead:
I understand what a reserve is. They also turn away the majority of bidders. Plain and simple, sellers avoid reserves for three reasons:
1. They put off a large number of bidders. I generally assume a reserve is higher than I'd be willing to pay.
2. Combative, back-and-forth bidding is what a seller hopes for. This is less likely at the seller's lowest willing value of sale, and more likely when the auction STARTS low, even if it soon gets higher. Low starting prices attract watchers, plain and simple. Reserves do the opposite.
3. A reserve doubles your listing costs, just about.
I'll let someone else below counter the rest of your statement, because all I would do is essentially repeat them.
I believe one of the reasons that may be selected for ending an eBay auction early is the "item is no longer for sale". There could be many reasons why that may be the case; it broke, got stolen, sold it to my Dad, or I just no longer wish to sell it. In any event, I don't believe it's against eBay policy to do so. It's not necessarily unethical for a seller to change his mind.
I don't care for reserve auctions because every time I've done one I get the endless inquiries as to what my reserve price is. Now I just enter the minimum starting price I'll accept and let it rip from there. If the item is also for sale locally, I'll state that in the description.
The "item is no longer for sale" is most often used by sellers who have storefronts, as well. I sell the majority of my stuff (musical instruments, usually) on forums. Because of the high fees, Ebay is my last ditch effort. If someone else wants it while it's on Ebay, I sell it to them and unlist it. It's my property, that's my right, and it's in no way against Ebay's policies. That's why the option is there.
All this said, we're getting pretty off topic, and talking about two very different policies (shill bidding vs removing listings).
"if I have an item that doesn't seem like it'll reach a price I'm willing to sell it for"
You knew the minimum you'd take, why not start the bidding there and quit wasting peoples' time?

Plain and simple, low starting prices garner interest. Usually, it'll result in the item being pushed higher than the lowest price I'd be willing to sell it for. On rare occasions, though, people just aren't looking for what I've listed, and that doesn't happen. In that event, I have the right not to sell my personal property for pennies on the dollar. There's a significant difference between a real-world auction and Ebay; Ebay's lack of interest in holding any buyer to their highest bid, or any sale at all, and the inability to leave negative feedback against buyers is a perfect example of that.
