While I agree on supporting the things you use. I don't think "the lists are everything". Quite the opposite, Its the blocking features.
For me I like uBlocks disabling Javascript with an easy click and the other granularity (popups, multimedia) it allows on a site by site basis.
I'm thinking of it this way. A guy builds a flamethrower to burn away the creeping slime that threatens to overtake your house. Someone else then supplies the fuel. You want to donate, but the builder says no. "The fuel is everything."
That's pretty much correct from one perspective. The flamethrower is built, just needs a bit of maintenance now and then. But its everyday slime-burning power comes from the fuel.
The lists are more like an automatic targeting system for your world-saving flame thrower. Both are vital since the slime killed everyone who knew how to use it, so now you have to enlist average people who only use them to clear weeds and snow.
When your flamethrower needs to shoot hundreds of thousands of little slime balls all at once using tiny little blasts of flame I think that targeting system becomes pretty damn vital!
To disable javascript for specific site in uBlock Origin, click the extension icon, then click the "more" button in the menu several times until all options are displayed (you only have to do this step once total, not per site).
Once the 5 top menu icons are visible, click the one to the right that looks like </> to disable javascript for the site you're on.
