Good ad blocking is an essential part of a browser. Even Google who is actively slow boiling the frog knows they can't just hard cut it off because the users will jump ship immediately.
Why should we let Google get away with this? I feel the right move is to proactively take steps that make Chrome very obviously noncompetitive. By not providing ad blocking at all or at least making it a much inferior experience. It needs to be obvious to the users, not just to tech folks.
