Frankly, it just doesn't matter at this point. The time to have done something about it was several years ago, it's a lost cause at this point. Whether you reflect and recognise your part in that, and learn and grow from it, is up to you.

I guess I would say: look at the big picture, Stack Overflow is almost dead. It's a bit like driving a car off a cliff because there's a post-it note on the wheel that describes that purpose of the car as to go inexorably in this one cardinal direction. At least the standards are established and thoroughly documented! The document objectively exists!

Also: I know several kind and smart people who have sworn off Stack Overflow forever, not because they misunderstand the purpose of the site, but because of the unkindness and nonsensical nature of the moderation. You are aware of the "popular art form" reporting these experiences - those with empathy pay attention to it.
