The advice on how to protect yourself from being spied on is essentially:
"stop using the internet; or use HTTPS - which is probably compromised anyway; or encrypt - which is probably compromised anyway; or use a VPN - which I will say next to nothing about"

Or it's just a hook for catching peoples' interest in participating in the group thing the hosts were organizing. (Yes, it'd be silly to devote your time to an effort like this to try to "help" Objective-C. But I don't expect anyone is really doing that.)
Please, this is HN after all! I would expect most of the guys and gals here to know about tools such as isup.me or other similar tools. I don't think we need a post for every other website that goes offline.
