What you said is true: I indeed cannot tell the difference between a v2 and v3 ad blocker. But that doesn't change OP's perspective that a v2 ad blocker is a symbol of the power user era. Power users often want customizability to an extreme level. Normal users who block ads simply install the extension and be done with it: they don't write custom rules or adjust the filters.

Not at first perhaps but they will notice when ad networks shift to take advantage of techniques that can no longer be blocked in Chrome.
