Ebay is a joke, they removed the listing because they do not allow bitcoin payments (i.e. they wouldn't have their cut from that...).
Not sure why that's surprising to you. They're running a business and charge money to use their platform.
And besides that, eBay will never allow bitcoin payments because they're irreversible. Eventually when we have layer 2 solutions running on the network you will see reversibility built into one of those, and they may allow that to be used...
