ebay finds that PWCC engaged in shill bidding?

[cannonballsun]

There seems to be two conflicting arguments that have arisen in this issue. One is that eBay is so huge (and they are huge) is that eBay would not miss PWCC's business, and because PWCC's business is so inconsequential to eBay, they would kick them off of eBay out of spite, in an attempt to harm a future competitor.
If PWCC's business is such a small thing to eBay, why would they bother ? Why would they see them as a threat to be concerned with ? As far as competition, almost every major card seller sells on eBay. They also sell from their websites, and some even have their own auction sites. Clean Sweep Auctions and Kevin Savage come to mind. Why doesn't eBay mind this competition ?
The fact that eBay gave PWCC a sweetheart deal, only taking a one to three percent commission (as has recently been learned), definitely makes you think that eBay valued PWCC's business.
So back to my original feeling, there is something more going on here.
