I get the impression that is part of Discord's intent they are signalling here and a lot of the response has been maybe a bit overly vitriolic in the face of that seeming message of "we are complying with the laws because we have to, but we are doing a bare minimum to do that". Especially relating those parts of the press release to the call for a Council of Teens and increased feedback.
It feels like a modern iteration of the game of way most bars check IDs: it's a bit of an honor system most nights and for most people. On days or events of increased scrutiny they put a bouncer out front. They make a show of doing it, but at the end of the day they want to sell product and not do paperwork, so it will be the bare minimum to keep the (international) law of of Discord's back. Discord seems to want just enough CYA much more than strict "we know the age of every user". This is the "we're going to put a bouncer out front" stage of the game, not the "police are at the back door and about to raid the bar" stage. It is interesting to me how many have read this PR and jumped to believing it to be the bar raid scenario.
