That's not entirely true at Amazon. It's expected for many of the more involved people in the meeting to read ahead of time, and at least be familiar with the subject.

At the same time, the time is given because not everyone will have time to read ahead of time. That 15 minutes at the start is their calendar block; think of managers who have back to back meetings all day.

It's not some referendum on people being careless.
