"Dumb pipe" sounds like they forgot about security.
I don't understand this perspective. Dumb primitives that are secure is _exactly_ how you build secure system!
You could describe this same project as "a smart pipe that punches through NATs & stays connected (...)" and it wouldn't be any more surprising or inaccurate than the current description. So maybe it is not that descriptive.
> ... that are secure ...
That's a huge assumption I wouldn't make after reading "dumb".
And from the article:
> Easy, direct connections that punch through NATs & stay connected as network conditions change.
This sounds more like a pipe that is trying to be smart. According to your principle, not something to build a secure system with.
