should we make a betting pool as to when this will be hacked and exposed? bonus if it was stored in a insecure method?
It's explicitly
not billed as a private communication system. It's for public interaction. It probably explicitly
won't be secured in a private way. Because it's not supposed to.
And it probably should be that way; if gamechat was end to end encrypted and nintendo had no access to the files, how would reporting work? Sure, a user could report on a chat they're in, but then it's not really end to end anyways, right? Moderation seems more useful for a public chatting system than not.
