I guess this site should be sent to anybody saying javascript should be blocked in web browsers... In the end whether a technology is used to track and exploit or educate and delight is entirely up to us.
What we want blocked isn't all of javascript, it's some of the browser APIs.
Again, it's all about the interface the browser provides. They could decide to remove this API for example: https://developer.mozilla.org/en-US/docs/Web/API/History
How is that any better than 'javascript'?
