GNOME Web (née Epiphany) now supports WebKit Content Blocker rules but sadly still comes configured with AdBlock rules that do not protect your privacy (they block some ads).
I’ve updated the instructions for replacing them with Better Blocker’s rules instead if you care about protecting your privacy.

TL; DR: Enter this a terminal window:
gsettings set org.gnome.Epiphany content-filters "['https://better.fyi/blockerList.json']"
PS. GNOME Web could have changed the default blockers but chose not to due to aesthetic reasons (“does not block YouTube ads”). Guess what? If you’re on YouTube, you’re already being tracked (and I’d love to know how AdBlock plus – which gets paid by Google and others to not block their trackers – blocks YouTube ads using WebKit Content Blocking Rules).

If they start caring about your privacy, they can do so by changing a single line in their codebase.
And that’s the last you will hear about this from me. I have better things to do than to try and lead a horse to water when it’s determined to eat sand.
@aral Have you heard about invidio.us as an alternative front-end for Youtube videos? I use uBlock Origin and Privacy Badger, they detect absolutely nothing, and I can watch as many "Youtube" videos as I want :)
@aral to be fair, for a lot of users blocking ads on youtube is an important feature.
This is a user experience reason, not an "aesthetic" thing. But I suspect you knew that already.
There's a balance to be found there somewhere, and different projects can see this differently. Doesn't immediately mean they "don't care about privacy".
I wish people in this sphere would find ways to disagree without immediately tagging each other with that label. This plays right into the hands of Big Tech.
