It’s already like that here, friend.
Lemmy didn’t take off until well into May 2023, despite being online and open source for over 4 years. The quantity of posts, communities, comments was very small for 4 years online.
Then everyone flocked out of hate and anger of an API money matter with Reddit.Then crowds got hate-filled and angry when Threads was launched by Meta/Instagram/Facebook on July 5. And crowds became hate-filled and angry over Elon Musk rename of Twitter to X on July 23.
Outside big growth in memes and shitposts, there haven’t been big numbers of people flocking here out of organic goodness on organized topics. It has largely been a HiveMind of hate as a motivation to come here since May.
Some good seeds have been planted since May, but the atmosphere of hate motivates change is pretty much Mob Mentality / reactionary.
I think the joke is how a pest exterminator is being called on an extinct species. Play on the mutual concept of extinction.
