(1) they probably shouldn't even have that data
(2) they shouldn't have it lying around in a way that it an be attributed to particular individuals
(3) imagine that it leaks to the wrong party, it would make the hack of that Finnish institution look like child's play
(4) if people try to engage it in such conversations the bot should immediately back out because it isn't qualified to have these conversations
(5) I'm surprised it is that little; they claim such high numbers for their users that this seems low.
In the late 90's when ICQ was pretty big we experimented with a bot that you could connect to that was fed in the background by a human. It didn't take a day before someone started talking about suicide to it and we shut down the project realizing that we were in no way qualified to handle human interaction at that level. It definitely wasn't as slick or useful as ChatGPT but it did well enough and responded naturally (more naturally than ChatGPT) because there was a person behind it that could drive 100's of parallel conversations.
If you give people something that seems to be a listening ear they will unburden themselves on that ear regardless of the implementation details of the ear.
