Dev, you're doing it again.
I gave you an article that provides some real figures, and all you spout back is pure conjecture.
"Blizzard is not paying for a 20 year contract". How do you know? Maybe they are.
Do I expect you to google up the exact details of Blizzard's contract with AT&T:ENS? No, I tried, and the press release provides no details. I just don't want you to continue this naive tirade about small profit margins and justification for monthly fees. Secrecy may be an issue here, and it could be that secret you don't want to hear. That you're being bamboozled.
Wikipedia is currently running a fund-raising campaign, and have provided details about their budget. Wikipedia is a fairly popular site with some heavy bandwidth requirements. Yet, Wikimedia's hosting costs are under $100,000/year for its umbrella of services that it provides.
I'm trying to build a case against this belief that companies pay out the ass for bandwidth. I think it may have been true back in 1996, but surely not today.
