If I'm bidding, and this decreases the amount of other people bidding on the item, I'm all for it.

If I'm selling, and this eliminates or significantly decreases the possibility of someone accepting one of my offers and not paying, I'm all for it.

I seldom run auctions. Nearly all of my listings (mainly vinyl records and comic books) are set to BIN. So, from my perspective, the prospect of less bidders "fighting it out" at the end is irrelevant.

There are likely some people with valid reasons for taking umbrage with this move. For example, combined shipping might take a little extra effort and a small amount of communication. Overall, though, this move seems like a positive step.

I imagine it will be looked at in a manner similar to the authenticity guarantee program. No matter how helpful it might be for the vast majority of users, there will be a few whose situation makes the whole thing a PITA. And, of course, there will some users for whom there will be no significant impact. However, it's change...of some sort...on some level. They'll gripe and grumble, b*tch and moan, complain for months...
