Social settings are "attention economies." Piling on to the argument adds attention to the thing you nominally want less of, yet are fueling. I generally try to not add to such situations.
I used to say "Fighting against the fighting is still fighting." If I am going to wade in, ideally, I should do so without being combative about it.
I have been debating whether or not to send the comment about how this is not accessible for the blind to a group I co-own called Blind Dev Works. Not sure if it is relevant to the interests of others there. I'm visually impaired and generally interested in accessibility, but I'm not blind, nor really a developer (though I actually want to learn to code and I'm trying to do something about that).
I don't know if it would just be seen as salt in an open wound or an interesting discussion.
