Regional servers are great, especially when it comes to regional laws and customs which people generally want applied (for example UK has quite strong Hate Crime laws, I’m sure DE does too).
I do think however, in early stages, I’d rather know who is running my instance and a few of their personal opinions. For example, are they going to defederate with an instance I quite like because of politics? We are really in early days here and these instances are very unstable whereas the mastodon instances have all been around with thousands of users for quite a time.
This, I wanted to join an instance with management I somewhat agreed with on matters of federation and had longevity. I didn’t want to join beehaw or lemmy.one for the first reason; and the others don’t really have the longevity to see how admins will react in certain cases.
