Adopting EVs is an important step imo. The primary achievement of going EV is reducing oil/gas use. Moving away from cars as a society is a separate goal that can happen alongside this. We can never make gas green, at best net zero. EVs on the other hand can be better, with electricity from renewable sources, to batteries made with better materials. Both things which are happening and actively being researched.
So we can make EVs much better environmentally, and reduce gas demand significantly alongside reducing car use. Because we won’t just stop needing gas magically, so replacing that is important for any transition away from it in the grand scheme.
When I looked into it, it appeared uBlock origin already does what no script does when you turn on advanced mode and block 3rd party urls. (medium mode) Probably need to block first party to get quite there but that’s usually overkill.
Now sticking with medium mode, most sites need a bit of fixing like no script did, but it’s all done in uBlock.
