From my experience most people just don’t know that it CAN be changed. They assume that there’s nothing to do about it, or that if there is you need to be a tech wizard to understand how. They know that they don’t understand how their computer/browser/phone/whatever works so they assume that even if there was a way it would be too complicated for them to even try. They don’t care to understand how it works, and that’s fine. I also don’t care how my microwave works as long as it does work when I need it to. There’s not enough time or mental energy to learn everything. But when you show them that all it takes is going to a website, typing “ublock” in the search bar and clicking a big button, then it goes from “probably rocket science” to “hey I could actually do this!”.
