Because they don’t get listed by browse.feddit.de you’ll want to browse https://kbin.social/magazines to browse “magazines”, which is what they call communities
e.g. !RedditMigration@kbin.social
or directly, https://kbin.social/m/RedditMigration
Why YSK: Federation literally just synched up thanks to the tireless efforts by @ernest@kbin.social over the past few days.
The two main devs seem to be Tankies or have at least close views. From what I heard, the hardcoded filter isn’t a thing anymore and was removed after heavy protest from other contributors. The good thing is that they don’t have any control outside their own instance and in worst case people would simply copy the project (since it’s open source) and move on without them. I hope that the different instances + community take a part of the donations to pay independent full time code contributors.
Thanks for the explanation!
