If it was automated and you still consumed the other resources (paid largely or entirely by ad impressions) then that case could be made.
Doesn't it also undermine producers ability to produce if you just get really good at quickly looking away?
It seems from your argument the "case could be made" that it's at least a little unethical to not spend at least a little while paying attention to each ad when reading a newspaper.
Like there's some scale where the left side has "0 attention spent, 0 ethical" and the right side has "maximum attention spent, maximally ethical".
