I’d agree that the overall trend for posters is probably similar and you have a fair point there. I wouldn’t say empathy is any different, but it’s important to keep in mind that different styles of social networks will absolutely attract certain types of peoples. I’m not making an assertion that this is good or bad, or who may be present in this community because of this, but it’s something to keep in mind as your average Instagram user and Fediverse user will likely have vastly different opinions, priorities, goals, and use-case for the platform.
I don’t think it’s fair to say that the doom and gloom is overstated. When you have a smaller platform and community, small issues are far more recognizable and have a greater overall impact if left unchecked.
