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.
What the hell? English has rules. If those rules aren't followed, it makes communication needlessly more difficult.
This isn't just a typo we're talking about. This is someone making a deliberate choice to be harder to understand because they see it as quirky and cool.
