As someone who worked on robot cars before it was cool (Urban Challenge, wut up), I can assure you, Net Neutrality has ZERO to do with safety in autonomous cars.
And if you think it has anything to do with it, you need to be kept far, far... very far away from ever working on them.
It's amusing and sad that you honestly think leaving Facebook is the same thing as cutting people out of your life.
I've been Facebook free for several years now. It feels great, and I didn't have to cut anyone out of my life to do it (who I wasn't otherwise already communicating with). Much less noice, more productive, both in my life and in my relationships.
I tried to replicate this and couldn't. It seems this isn't so much a Wordpress issue as it is a poorly-setup-webserver issue.
If your nginx/apache setup is set to have "Host: * => wordpress", you're doing it wrong and this issue affects you.
But if you setup your server as you were supposed to, i.e. matching on the Host (server_name in nginx) to route to your blog, then obviously SERVER_NAME cannot be overwritten, and any attempts to exploit this will result in 404.
The article never substantiates the claim that "NoScript is harmful". They talk about NoScript's website serving questionable software, not NoScript itself.
