I think this all dates back to the end of Halloween in the Castro[1]. This was back in 2006. S.F used to throw a huge awesome LGBTQ themed party and then some gang members decided to attend. Gang members being gang members, one threw a bottle at another and 9 people got shot. They shut the whole thing down that 10s of thousands enjoyed hugely because of that one incident.
I'm thinking that the extreme overreaction was because if this incident had started a rift between any group that was not a white supremacist or Christian group and LGBTQ+ this would have been catastrophic for intersectionalism. So they had to shut it all down. The suspects were never arrested or described any more in news articles than being associated with at least one gang.
Thus, I think the end of fun is to prevent any incident between the great mass of intersectionalist factions that don't like each other, or have irreconcilable differences in real life and must exist in carefully managed online spaces and social interactions in structured environments in order to present as part of a unified woke coalition. The contradictions are so great between all these groups that more and more rules must be added on top of rules to keep all the conflict from escaping out and piercing the image of a bland unified morally righteous whole.
