alt Hacker NewsThere are valid reasons for using ad blockers, hence why the general US Intelligence Community both uses and recommends the use of ad blockers "as a critical security measure to defend against "malvertising" and data collection threats".
All other arguments are moot in the shadow of this. However, if you're talking about how a media company can stay afloat without advertising, then you're getting very much closer to ethical arguments. I currently just point to the first paragraph in such an argument.
The advertising industry needs to sort out its inability to appropriately and safely scale before any ethical arguments are able to put roots down.
I hear you on malvertising and overzealous data collection. I certainly think online advertising needs to be carefully regulated for essentially safety reasons. But in an ideal world where such regulation was firmly in place, I think it would not be appropriate (because it would not be necessary) for government or influential industry groups to endorse ad-blockers.
BTW I've added an ETA to my original post with my reasons.
