Ah, it requires at least 8 million users[0] in Malaysia and they have a list. I was wondering how Hacker News etc. were going to comply.

The list is pretty small, so I wonder if this just drives users to other, smaller platforms. That said, the list of platforms includes all the biggest offenders of engagement optimization, so it feels more like a ban of addictive social media than all social media in general. But it's also interesting they ban messaging apps, which I assume parents use to keep contact with their kids.
