Have to agree with Saul on this. We are part of the 300 million. My daughters have their dance class on Zoom once a week. So not just our family, but most likely many of the other kids in the class as well are once or twice a week users. Other than dance class, we use it to see family maybe every other week or so. Just one example, but multiply it by the number of new users in similar and You can see how this more than offsets those using for multiple meetings a day.
Combine that with the previous quarter number of 10million, of many were meeting multiple times daily - is a non-issue or even positive imho. I see nothing shady on their part. Apples to apples comparison.
