I guess the beautiful thing of being federated is that the content is separate from the software. If people enjoy the software but find kbin.social to be too unstable, they might very well jump ship to https://fedia.io/ or something (or even start their own instance), and we will still get to enjoy their content. :)
I don't have much patience for people complaining about how their instances are being run considering how easy it is to move somewhere else. Discussions and constructive criticism is of course a different matter, but the beauty of the fediverse as far as I'm concerned is that you can take the "if you don't like it, go somewhere else" attitude to the extreme without really being a jerk. :)
