The hamster forum (like many other forums, that one is just the one the papers could make a clickable/shareable story focusing on) isn't being shut down by the government. They are shutting themselves down as they do not want to run the risk of accidentally breaking the law which are so vague that they arent even sure what moderation decisions are to be made. And probably because it requires constant supervision. Just fyi.

It pushes all communication into approved and surveiled channels, the existing big players. A win for govt, and a win for Big tech because they get more eyeballs to feed ads.
