Facebook workplace and Yammer are from different organisations so it's unlikely that Microsoft will give much consideration to Facebook workplace.  It's like the comparisons you get between Teams and Slack (Teams in my opinion is now on a completely other level to Slack though).


I do understand where you are coming from with the Teams vs Yammer thing though.  It's very clear from Microsoft that Yammer is here to stay for now though,  especially as it now has the connector for Teams.  Whilst I don't see a huge interest or demand for Yammer from my own customers, it's clear that it does have a niche following and that Microsoft are committed to it for the foreseeable future.
