My first impulse was that you made a great point. But on further reflection, a newspaper ad page really isn't a good analogy. If you paid for a listing, whether as a regular local citizen wanting to sell your car or a business wanting to attract customers with graphics and such, even though you had to share the page with others, the listing space you paid for was yours alone, with a boundary around it, and nothing interfering inside that boundary.
Of course the use of screens and internet has completely blurred the definition of "listing" and "page". And that's true for all online venues at this point. But eBay blurs it worse than any others, makes a mockery of the whole concept of an item listing. And for buyers viewing on the app (which most of them are now), it's farrrr worse than on the website, just a total joke.
Here let me show you, using one of the OP's listings, compared to a similar item on another venue.
So here's the OP's. -These are screenshots I took scrolling down, length-by-length, from the top of their listing to the bottom (or far enough anyway). Note how you don't even get to see the Item Description without clicking to another page, yet apparently there's plenty of room to show other listings and stores, and they're totally MIXED IN randomly with the OP's segments. Look at what an insane amount of scrolling a buyer has to do, to see all the information they might want to know about this item and this seller. And that's IF they don't get confused or distracted before scrolling far enough. 
Now look at how a listing appears on the Etsy app. -Yes unfortunately you have to click to read the item description there too, but at least the first 3 screen lengths are devoted to nothing but this item.
And the 4th screen? -Well how about that?!! Links to more of the seller's own listings! How awesome would that be, @clothingniche ?
Only AFTER those 4 scrolls does it start showing paid promotions of other sellers' listings. And even then, they keep the ability to click and buy the (actual) listed item 'sticky,' at the bottom of the screen.
