I think the discussion might be more focused if you say what your
goals are.  Then we can compare the licensing plan to those goals.

If your goal is to be the dominant PIM on free software platforms,
then copying MySQL's licensing seems reasonable.

It's worth noting that MySQL is only mildly useful by itself, and is
normally part of a larger application.  I would have thought that a
PIM would be quite useful by itself, and would not normally be part of
a larger application.  So focusing on forcing people to release their
entire application may miss the point.  Or, more likely, I have missed
the point.
