I honestly don't think this platform specific language needs to stick around. I really think a lot of that originated as marketing and has always felt somewhat unnatural to me. Particularly because the threadiverse/fediverse is made up of many interconnecting platforms it's pretty clear that these terms will cause more friction than anything else.
This is also why I prefer lemmy's communities to kbin's magazines. Communities feels more like a universal description while magazines feels like platform specific language.
