But from my experience, “money makes the world go round”, meaning: If there is a legitimate business case it is more likely that such a website or instance will stay online, whereas a lonesome enthusiast will likely loose interest after a while. And then its all gone (at least for that instance)?
Thanks one of the biggest strengths of the Fediverse. One instance dies for one reason or another, but the whole thing is impossible to kill, because it is not hosted by one single point of failure (like reddit).
I had the same concerns, but then I realized I just... can make another account if that happens, on a different instance. I tried to pick one which is hosted by someone who has a track record of keeping stuff online for a long time, but if Milan ever decides to shut it down, it will be a very sad day but in the end... it's not a very big deal. There will be others, and the Fediverse will still be alive.
Same goes for your concerns about visibility and banning. There are all kind of instances out there. Pick one which fits your needs. For some people this is a very restricted space, some want to see ALL.
Centralization is of course easy because everything is done and decided at the same place, but in the end, every centralized service is doomed to fail at some point. Have fun here. :) Keep an open mind for the concept of the Fediverse and you will be fine.
Working it Austria at least, but of course more limited supply. Would love to find a good Audio Book Service which is not Audible. :(
