You're casting too broad a net here. I don't think this article is about pedantry. There is a time and place to be pedantic, just arguably in none of the given examples. The place to be pedantic is to point out sloppy thinking. Sometimes you just need precision, and it's not enough to be "mostly right".
I don't think "pedant" as a personality trait encompasses people, who are only pedantic in necessary context. Your answer thus might be a bit... pedantic? ;)
So I could point out that you started your comment with “You’re”. This statement is 100% correct and it’s pedantic. I bet you can’t argue that(but it’s moot! what has it to do!? Whatever the context!)
I agree with you, the problem is not being able to synchronize with the goal or hierarchical chain of logic behind original statements, leading to remarks that are irrelevant, and I think it’s merely considered “pedantry” here by the looks of it.
