I’m confused about what they would be suing for? Based on the example of Nintendo, if people were sharing links to download Switch games or something, yeah then you would have a copyright concern.
But Nintendo can’t sue anyone for simply talking about Nintendo products. Forums have existed since the birth of the internet, and they’ll exist long after whatever happens to Reddit, for example.
I had to remove it from my Home Screen just because of the muscle memory. I’ve opened and immediately closed it so many times today.
But if they behaved like this, other instances would just block them from federation (“seeing out” to other instances) and they’d be isolated in their own little silo. That’s the beauty of federated networks - bad actors will be naturally pushed out and isolated.
