Noscript is besides the point
Most people here are fully aware of how to mitigate javascript flaws, we've been doing so for over a decade. I'd even go so far as to say most of us know how to surf using Microsoft Firefox Installer without getting enough malware to warrant a rebuild.
But this isn't the point. The point is that computers have been sold for well over 15 years on the principle that everyone should not only have one, but they should use it to communicate with their grandchildren or college friends and perhaps learn a little bit about the world we live in.
Worse they are then told a complete crock of shit when they're told that the expensive internet protection package they have bundled with the PC is going to make it safe to do so. Would it be so hard for one of these PC megastores to employ someone who has a clue and will not let anyone take a PC home without a decent firewall in place?
No because that would be something close to customer service, so instead they'll sell a dog turd of a system and charge a premium for it. Fact is if we are serious about continuing to earn our livings doing this or supporting the businesses that do this, we ought to be able to say with some confidence that you can surf corporate websites with no need to set up firewalls or install and then spend days answering questions from anti-javascript addons.
Noscript is not a piece of software you can give to someone who doesn't know how to copy photos from a digital camera memory stick. You might as well install it with a Simplified Chinese language pack for all the sense it will make to those that need it most.
If computers are the appliance that PC World and Best Buy claim they are, they should work with zero configuration required. And if they aren't then they shouldn't be sold to people without a cigarette warning on the box that tells them they'll need to spend months learning how to surf safely before connecting to the internet.
My own theory is that every PC should be bundled with 100 dvds stuffed full of the best porn and the network card safely configured with a screw driver and a mallet. Because what need for the internet if you've got what you wanted from it already?
