Basically, the tweet is referring to another tweet made by someone complaining about the localization of Daybreak II, where a 15 year old girl, god forbid, used internet slang in a setting with.. the internet (and twitch streamers, vtubers, virtual reality, guns, airships, etc)
the same character uses god damn teddy bears as attacks. it's supposed to be goofy and cringe. it's in-character.
there are far worse localization choices to focus on (Elaine's title being changed from Sword Maiden to Beauty Blade, for one)
