I think mattermost is an appealing alternative, but don't think it has the potential to dominate the enterprise market, but more develop as a successful niche player for the most security conscious companies. It's also something I imagine the other players will address at some point for some kind of a premium enterprise offering.

You do not even have to be too conscious about security as a company. A lot of contracts with companies and/or government agencies in the EU (at least in Germany) require that you handle data according to EU/German laws. If you use a SaaS which does not host in the EU it is a lot harder to satisfy those requirements. To be compliant it is a lot easier to spin up your own Mattermost in a data center here.
