Maybe that's why metabase was hacked - to conceal sale of data. "It's just a hack, it happens, we fixed the hole, nothing to see here until we find the next buyer".
So your argument is that ID checks are necessary simply because they are possible, and not a privacy invasion?
The question was why they are necessary.

Why are you gaslighting HN?
The underage crowd can't enter a space that is specifically exists for experiencing the prohibited behavior. Where the internet is a more general space and we are restricting anyone that has not proven to be adult. And what are we restricting them from? Posting/publishing & accessing content, that sounds like age based censorship.
Would someone underage have less rights to receive or publish unpleasant/controversial topics under the First Amendment? I think you need to have a very strong case to undermine those rights and I just don't think "might protect the kids" (which is debatable) is strong enough.
