Well we had our first instance of someone accidentally publishing a PowerBI report to a public Yammer Group...
We have Group creation restricted to two admins. So Group provisioning occured on like half of our Yammer groups, and not the other half. Since I created this particular one, everyone can see and publish PowerBI's, and there is nothing that actually tells you who did it.
I really wish there was a way to disable or hide some of the supplemental services that have no business existing in our environment (like PowerBI workspaces for public Yammer groups.....)
Super annoying...
