This is whats kind of not clear to me. While its clear what the benefit is for lemmy.world or some instance you move from, its less clear what the benefit for the individual moving is such as myself. I have more risk, its a hassle, the smaller server might itself get overloaded or break. Sometimes it feels ‘safer in numbers’. Unsure. Feels like I would be best off if everyone else moved and took on the risk while I stayed and reaped the benefits of them reducing the load rather than me doing it.
