Just got the new UI design for Slack. They seem to have combined "activity" and "notification" indicators on the desktop app icon and the browser tab.
My app's notification count went from 0 to 84 suddenly. Now a missed direct message and every little activity (the 100th reply on a long thread) look the same.
This new design seems intentional, perhaps for some PM to increase "engagement" numbers. In my opinion, it seriously dilutes the meaning of the notification indicators and is yet another user-hostile dark pattern on the path to enshitification.
