From the looks of it, everyone quickly agreed that this list was inappropriate and it was shut down promptly. The drama didn't start over that, but exaggerated claims people made such as "this is the road to genocide", as well as connecting this list to some mass-shooting, as well as some lingering conflicts such as whether or not the title "it doesn't have to be crazy at work" – a book published by basecamp – is ableist or not.
People act like "haha, this name sounds funny because it's similar to the English word [...]" is a huge deal and existential threat. It's ... not really. It's just inappropriate for a number of reasons, not the least of which is that making fun of your customers for any reason is not a good idea. People seem to have lost perspective here.
DHH tried to inject some nuance, and paid the price it seems :-/ All this incident has accomplished is turning off people, in spite of clearly being sympathetic to it to the important bits of social justice.
The social justice movement is eating itself from the inside out with stuff like this.
