I agree, and it's very frustrating that most articles are unreadable unless I change their font or colour choices. I should have to have an extension installed that makes text readable. And, unless people speak up the people who create these broken designs will never know that they are choosing to say "fuck you" to a sizeable proportion of their audience.
But: it's about the least interesting thing that can be said about this article. And whoever is responsible at the New Yorker will never see these comments.
I think dang has said these kind of comments are off-topic.
I personally don't think "The choices you've made exclude part of your audience, and may not be compatible with laws around accessibility" is bike-shedding, but I have stopped commenting on design choices.
