There was a recent related discussion on Hacker News and the top comment discusses why this sort of solution is not likely to be the best fit for smaller organizations. In short, doing it well requires time and effort from someone technically sophisticated, who must do more than the bare minimum for good results, as you just learned.
Even then, it’s likely to be less reliable than solutions hosted by big corporations and when there’s a problem, it’s your problem. I don’t want to discourage you, but understand what you’re committing to and make sure you have adequate buy-in in your organization.
It’s probably more fair to call its claim of being decentralized fake or disingenuous. There doesn’t seem to be any way to participate in the ecosystem without going through the Bluesky relay, a central point of failure with strong incentives to eventually do something shitty.
