It works exceptionally well for Slack as we've seen over the years. Someone in your $group uses signs up for the free tier, gets people using it and then you've got to pay through the nose to access any history.
At least slack is clear upfront that this is going to happen, mattermost just did a rug pull and removed history from users who previously had access to it.
Isn't that just the Oracle method?
