First of all, I agree that slack org chart is buggy. But usually it’s randomly affecting anyone, not showing patterns like what we observed recently
If the slack org chart sudden change means anything, i don’t think it’s comprehensive. Not everybody who will be laid off were shown as orphaned. But people who were orphaned may have some changes coming to them as something changed in AD that triggered some changes in okta that somehow, maybe unintentionally, got reflected in slack org. This change may mean the person is changing manager/group or potentially will get laid off.
I suspect that whatever changes that they were doing in Slack were interrupted by the commotion in the rumor site, and the activities stop. That maybe a reason that these changes were not comprehensive.
