By now a browser is just a UI platform for a website, so if the website doesn't give you the content, the browser can't extort it from the server. So far we can filter out some ads because for sites it's just cheaper to use off-the-shelf solutions from ad networks, which are the same for everyone, and to preserve accessibility via HTML. Enter heavy randomization or the canvas, and filters won't work. Look at Yandex: it took the fight with adblockers seriously, so uBlock's lists finally gave up—it just was no use. If you try to use customization via CSS, on some modern sites the crazy mess of divs with cryptic classes already makes no sense and doesn't lend itself to CSS selectors.
