The federated concept is nice. But I feel like what will happen in the end is that most of the content will end up on few instances. This still gives power to the owners of these instances, and if they delete the instance a lot of people would lose accounts?
What would be your ideas to improve this and have less centralization?
Content is basically avaliable to everyone regardless of what you end up choosing. At worst, they can block an instance from interacting with another.
Most problems can just be solved by moving to a new instance that meets your needs. Or if you really must, make your own with your own rules.
My concern is an instance shutting down and losing access to all that information. I can always make a new account, but losing all that info from the entire instance could be a big problem. Maybe by then tho people will archive them somehow.
The most extreme case I can think of would be instances blocking everyone but themselves or a few select instances, and forcing everyone within them to follow their rules to access it. But I feel like that would be hard to pull off, people would just jump ship way before it gets to that point.
