At some point, users of the mastodon.social instance where most of the left-leaning crowd gathered, got their admin to preemptively silence the inditoot instance on mastodon.social[1]. This meant that all toots from the inditoot instance were effectively blocked on mastodon.social, and the two sides were operating in separate bubbles.
A few months later, the Indian userbase on both mastodon.social and inditoot was dead, and everyone was back on twitter, fighting and clawing and tearing at each other.
Moral: If you remove the communication links between those nice round planets shown in the animation, they become drab and dreary, and not worth having at all, and you're back to twitter. If you keep the links, then there's no difference between federated instances and twitter, and you're back to being twitter anyway.
