I'm guessing I'm the one who has the name you can't say?
ECW was a partner of WWE's against WCW, but it really was more of development territory for WWE. Vince funded them for a while and let guys still under contract to WWE work for ECW(Justin Credible and Sunny are examples). From what I understand, they never just took guys from ECW. They always let them use WWE talent or gave them talent or gave them money in exchange.
I don't think WWE going towards a more "Hardcore" product affected ECW as much as people think. I mean, ECW towards the end wasn't that great. Plus, Heyman's horrible business sense didn't help either. WWE just saw what the fans wanted more of and gave them that. Smart business move, really. ECW died because of ECW. Obviously WCW and WWE didn't help too much, but the blame rests mostly on ECW themselves, imo.
