blaine@Gargron like it or not, "Mastodon" isn't just "Mastodon GmbH" or even just the software – it refers to the Fediverse in common usage. That's a tension that's not going away, and I profoundly worry about the your suggestion (understandable, at some level) that your org will exert control over what does and does not constitute "Mastodon."
