Perhaps an understandable (though not very charitable) reaction if you cannot see yourself having the same viewpoint. But I think the existence of other people who believe they would have the same viewpoint means you should view it as less far fetched, or not far fetched at all. You might discount some of this as people incorrectly believing they'd take a view that they presently view as "more moral" without actually understanding how they'd behave.

I've had the opportunity to work on some tech that was similar to adblocking, and, without moralizing, I found it highly stressful and quickly chose to work on something else. I encourage you to read my reply here: https://news.ycombinator.com/item?id=10240713

The reason I dont see that viewpoint is I feel it doesnt make sense- See this comment : https://news.ycombinator.com/item?id=10240696

The kicking kittens analogy is bad -- we all know we aren't going to like kicking kittens. As I said, I briefly worked on something similar to adblocking. I didn't know it was going to make me miserable until I did it (for maybe 2 months, maybe less).
