No, that’s a bad analogy. A closer one with your context is having a bad breakup and then getting into another relationship and moving in with the person, where your share stuff about your prior life along with other stuff.

But a better analogy is people living in an apartment building who get together for social events in the common area for years until the management starts doing shitty stuff, increasing rent, etc. A hunk of people decide they aren’t taking it anymore, so they all move into the newly built apartment down the road that doesn’t have many people in it yet. The new place also has community events, and now it’s mostly people from the old place that are talking about what happened in the old place.

Bad breakup, eviction, or whatever, you can’t expect a group of people who had a bad experience together to just stop talking about it in a few weeks. The vast majority of Lemmy users came from Reddit. It will die down when people really have gotten over it.
