Why Would XO do That? – continuing saga …

Well, we thought the XO issue had been solved, but apparently it is only solved for one customer.  The original customer that I posted this on is still waiting, and then, yesterday XO told us that they are planning to disconnect a working client of theirs because the client ported the number to ATL.  Does XO really not want these customers?  Are they really that concerned about an independent RespOrg?
