They're also wrong, open networks can die out. Usenet died out to proprietary forums, to the point where we've been left without satisfactory replacement. Email might not be dying out but it's being assaulted on all sides by proprietary messaging systems. Some of the largest recently acquisitions of companies have been proprietary messaging systems.

Bitcoin is potentially vulnerable to a more easy to use (or more easy to scale) proprietary version.
