IMO content over style. Nobody owes you adherence to a particular set of rules, nor do they owe you their thoughts at all. If the writer's style is a bridge too far for you, kindly just close the tab, don't complain about it. Certainly don't use hateful words to describe them.
Remember, the same English teachers who taught you to capitalize also taught you that there is no singular "they" and that you should use "he/she" instead.
I sure hope we are allowed to criticize writers’ styles.
