> you’re punishing everyone with having to back-read.

What? Instead you are punishing everyone to sit on a meeting, hearing two people discuss something that could have been a dm. I get that some people prefer meetings but to me every meeting with more than 3 people is a massive waste of time

When you get to that point, those two people should take the discussion outside of the sync call. The purpose of a sync is to figure out whether your current work is on track and, if not, who and what is needed to fix that.
