@MandatoryIDtag Devs can say whatever they want, but they should also expect those statements to have an impact on an already volatile player base.
Making fun of your players on a personal level, and then backing it up and digging in and attacking even more, isn't just about the words. It's basically telling the player base "the situation you're going through is humorous to me and I could honestly care less what you think."
One final distinction that should be made is that the player in question never @ the dev or told him to do something to himself directly. He was responding to/conversing with another player, not the dev. There is quite a significant difference.
It's like if the government were discussion sanctions against Amazon's workplace conditions and then Amazon's official twitter feed started making fun of their drivers having to pee in bottles.... oh, wait. Yeah, that turned out well.
