Amazon’s policy is even better than that (IMO). They know that no one reads things before meetings, so it’s accepted that everyone will quietly read for the first part of the meeting (as much as half the total meeting duration). Then (and only then) when everyone has finished reading the same material does anyone speak up to ask questions or share input. Saves a lot of time in meetings, although it adds a lot of time in preparing documents. I suspect it probably nets out to positive time savings and am confident it results in more informed decision-making.
