This is such an utterly disingenuous argument. I'm becoming more and more convinced as time comes on that analogies have no benefit whatsoever and just become a tool for people to warp the argument into something else.
The only difference with modern web portals is centralization, which allows the government to seize it in one chunk, vs distributed amongst N different organizations, but that's really only marginally more secure, because the government has no problem bulk subpoena-ing all of the major service providers.
The only real protection is to use pseudonymity everywhere and to never reuse a pseudonym between two different services.
There's no denying that government military funding helped kick off Silicon Valley, as did DARPA and the Internet, but to say that means today's entrepreneurs in the valley are apt to serve military war interests is pure guilt by association, and a weak link at best.
They are as "apt" as anyone else, which is to say very; The government wields big carrots and sticks.
It's like saying that a company that provides paper, pencil, and mail delivery is building the greatest instrument for evil and authoritarianism, because it becomes a channel the government can intercept.
Every technology has upsides and downsides. That the state exploits the downsides doesn't make the provider or inventor "evil".
