There is no security on the Internet. None. Nowhere. Act accordingly, or have no complaints.
EBay is up, it's down, it's all around. I imagine that they will take extra encryption steps in future, but those will also be breached eventually. There really isn't any kind of permanent solution.
Trailboss, you're correct. The situation is way worse than any of us can imagine. Just the tidbits that I can squeeze out of my security contacts are enough to scare the hell out of me. The Internet is the biggest Trojan Horse in the history of the world and our entire infrastructure is tied to it.
