Are they? On client side, technically it is easier not to execute scripts then to do so (despite the UX of https://addons.mozilla.org/en-US/firefox/addon/noscript/ might let you think the opposite). Technically, with DOM inspection one can also easily filter out elements you don't like, both on client and server side. It is literally one XQuery/XPath away.

The problem is that most modern "apps" stop working once you prevent them from exchanging data with third parties or using nowadays-standard APIs such as XHR or Websockets. This is why a radical cut was chosen by Gemini.
