A 45 minute "round table" with multiple rando masto instance admins? That doesn't sound like enough time for the table to get very round.
It sounds more like 5 minutes introduction, 30 minute presentation by Meta, 10 minutes Q&A. But oops our presentation ran just a bit long, and I really do have a hard stop at noon so we really only have about 5 minutes for questions thanks for all of the valuable feedback we'll be sure to circle back offline.
Broadly speaking it sounds a bit like Antitrust https://en.m.wikipedia.org/wiki/Antitrust_(film)
But I haven't seen it in quite a while so I'm not sure how well specifics line up.
