I will allow one more meeting to start a new sprint and end the previous one. Everyone should have prepared ahead of time to report on all their sprint items and whether they were completed, if not why not, and to present the work they will be doing in the next sprint.

If the Scrum Master or whatever their title schedules any other repeating process meetings, fire them.

Be the change you want to see.

there should be only 3 regular meetings in an agile engineering team - weekly iteration planning (1-2 hours max) - daily standup (15 mins max) - weekly demo & retro (1-2 hours max)

literally everything else is work off the kanban board or backlog.

in my teams everyone was told to decline all meetings unless it explicitly led to the completion of a weekly planned story/task. this way all meetings for the team have a clear agenda and end in mind.

for mandatory external meetings & running interference with external parties, there are ways to insulate the majority of the team from that.
