The author makes good points, that the only way such surveillance could be allowed to occur is with informed consent, and that's what Snowden gave us the opportunity to do.
I respectfully disagree. I think that, generally speaking, network surveillance without explicit informed consent might be OK as long as all the information is made publicly available. Especially if it is information regarding public officials, which are paid by the public to perform their duties.
I know, this is a radical viewpoint that runs counter to many privacy advocates here. Still, i think if you want privacy then shut the phone down and have a private voice conversation with someone at a restaurant, or something like that. But if you want privacy over the internet to somehow take advantage of your position, hide your stash of illegal cash, or anyhow break the laws you don't like
(and by the way, if, say, some laws are so stupid that you need to break them often, then it's time to change the laws, instead of advocating privacy so you can hide the fact that you broke them).
