Nine people on the screen is a nice ratio, and if the 10th person says something, they take the place of the person that hasn't said anything the longest on the grid.
There are other reasons I dislike Teams, but this isn't one of them.
This is just a recipe for excluding people who don't speak up. In a larger meeting I particularly want to prompt juniors to speak up, for example. I also want juniors to see each other so they feel more a part of it.
If you are only interested in the last person to speak that's fine but you might as well just use a voice call for that.
I turn my video off during video conference calls, but others may not feel they have the autonomy to do so.
