Are you implying that native advertisements aren't ads, or are more acceptable kind of ad, or are impossible to block? Because none of those things are true.

Native advertising is probably the worst kind of advertising. If I see a website or magazine publish an "advertorial", I'm never going to trust anything they publish from then on. It completely undermines credibility and only makes sense as a last-ditch moneygrab. It's not even worth blocking because it's a useful red flag.
