I can accept that you feel that way, but I don't really understand why. I can't see who is hurt by it.

As a seller, I don't care a lick how someone submits their bid, and assume that one way or the other, serious bidding often takes place in the final seconds of a week-long auction.

Ditto on the buying side. I accept that my bid will likely have competition, either from other snipers or from people tapping their phones. In fact, it was a seller who first told me about sniping when I was new to Ebay, and told me that's what I should do if I want to win his auction.
