The article title is simply wrong. Jobs promised to make open standards, not open source.

To people talking about Virtex and server hosting: an open protocol doesn't imply that that a server must handle traffic for free. Your webserver runs an open protocol (HTTP) but only allows connections from authorized clients.

Video-chat providers could sell access to their chat-hosting, or make peering agreements with other providers, like the regular Internet.

But Jobs wasn't really interested in that; he was riding a marketing wave making promises he didn't have to keep.
