Could just as well have gone the other way though. Sassy CM telling some loud, annoying, entitled brat to git gud or cry more? Instant cool-dev meme. But if a lot of people feel similarly you get outrage and controversy. Just depends on the local culture on that particular day in that particular place.
It’s cool to be rude as long as you also feel that it’s warranted. It’s cool to offend people you don’t like or deride ideas you think are stupid. Everyone isMost people are always just one wrong audience away from being a horrible person.
Of course CM or PR staff have different expectations, but I can understand why they might make a gamble sometimes trying to be cool and causual.
