It seems that the issue was resolved behind closed doors, so it could have been resolved behind closed doors to begin with, and then if the defederation was to go ahead simply announce the defederation.
Making an announcement "it will be defederated in 48 hours" made for this weird countdown drama thread (we even had programming.dev people show up and be sad about defederation!) that didn't really go anywhere, and then y'all just locked it when we refederated and made it clear that you were never interested in input and you'll be running the instance as you please (which is well within your rights of course). So what was the point of the thread?
I can see how it is nice to have warning if a community you're involved in is going to be defederated, but it also drags drama to our nice little corner of the fediverse, and pins it at the top of our feeds for all to see. In fact it shows up as the top of every feed for me, Local, All, and Subscribed. I can't get away from it.
Every time these threads show up they end up blowing up. Honestly, if you didn't make these threads, I wouldn't care who you defederate. But because the thread exists, I have to come in and I have to have an opinion. That's a personal issue and I recognize that, but I would hazard a guess that I'm not the only one. People who have never interacted with Blahaj nor the instance getting defederated show up in these threads sometimes. These threads invite drama, and for me personally, whenever they come up they make this space feel significantly less safe and make me want to leave Lemmy as a whole because it feels like it's just nonstop defederation drama for days at a time, but it's pinned at the top of my feed.
Maybe these threads actually provide utility, and I should just take these threads as a sign I should take a break from the Internet for a bit. But to me, they just seem like they're all downsides.
I'd just like to say that I really appreciate how this was handled.
In order to curate a space like this, it's important to address issues swiftly and decisively, and I would absolutely consider questionable behavior on the part of an instance admin to be a major issue. It's not really feasible to start a discussion with every instance, nor should you be required to - especially when it's not clear that such a discussion would be welcomed in good faith.
The 48 hour notice is an effective courtesy for local users, and in this case resulted in immediate improvements on the other instance, which would probably have lacked motivation without the impending defederation. And with the problem addressed, the defederation was just as swiftly rescinded.
Well done!
