accounts doesn't mean the same thing as current or active users. a company very likely doesn't delete accounts right away or at all, even if the service has been cancelled. for example, a few years ago microsoft's live ID system had well over a billion accounts. but MAU was only around 450M. and that is with culling / deleting accounts after a year if they were unused.

While I agree the two are different, I also think in weeks case accounts could translate into multiple users. I know for a fact that my wife and her sister both share a weebly account for their business and I believe they have to share a login to do this.
