I don't think that your concerns will happen. As the fediverse could be easy replicated and it is no problem to run an own instance federating with whatever you want AND be part of the rest.
My guess is that we will see more instances with different tastes if I may call it this.
By using tools like kbin you are also free to assamble the fediverse you want without the need to follow a single instance only.
Thanks for doing this ama!
Without revealing to much, what are your customers or is it pure research based?
A second question, is the code generated vulnerable often because using certain programming languages that have "known" problems or are the problems coming mostly from bad coding habits?
I think we cannot tell, yet. For now everything looks good, as you said, ooen protocol and decentralized.
But when the hype hits then suddenly money could talk and things could get worse unfortunate.
Lets hope the best and use it while it lasts
I use the kbin website saved as an app on android home screen. Responding via kbin actually. So I can collect or respond to information from lemmy and mastodon without jumping around.
Other than that I also have jerboa installed.
