Right, and I'm thinking this is not actually a solid way to protect fediverse from what is happening everywhere else.
We can all create instances, but there needs to be engagement for it to matter. I'm not looking at this from the point of view of "what can I do to enjoy my time on the internet while my rights are taken away and I'm told my sister should go to jail for wanting an abortion"
There is a pattern that occurs with seizing digital spaces. It starts small. They begin dog whistling in small communities. Not enough to get banned. Just enough to get reactions. Based off the reaction they target a few of the weaker ones. Whistles get louder. They link those to their influencers who post to their base. That base begin to show up and the community begins to fracture. Mods get overwhelmed. Ask for help to increase mod team. Some of the new mod team are the very people poisoning the community or are affiliated. The new moderators make it worse. Users begin to block or leave the communities. More dog whistles. More growth from the right until the community is captured. They move on to target another bigger community and are now using the first community as a pool to feed into the bigger one and turn it. So you can de-federate but nothing really stops the attacks. There is no real mechanism right now to guard against what has happened as far as I see it.
If lemmy were to grow as big as other sites, it will be just as likely to swing hard right unless something else is done.
