The job of a PM is to ensure the team is engaged in the highest leverage activities.
Simple example, is the most impactful thing Microsoft's browser dev team could do is working on EdgeHTML or is it contributing to Chromium, the defacto standard in desktop browser engines? https://t.co/Jmvp4XfxrV

This was a bad long term call in my opinion. Monoculture is like the days of IE6.
Doubling down on a browser that end users & developers aren't interested in isn't a better call unless the goal is simply to have a unique code base as opposed to having meaningful impact on the world.
