It’s a shared to-do list with a biweekly meeting to review and cleanup the to-do list, a biweekly meeting to select items to be worked on in the next biweekly period, and a biweekly meeting to discuss how the last biweekly period went. And a daily update meeting.

Exactly this. When I used it, that's exactly how it was, and honestly it was great compared to the utterly chaotic and disorganized method of organizing work I've seen in other workplaces.

It seems like all the people who absolutely hate it worked in dysfunctional places that completely misused the tool, or treated it like some kind of religion.
