There's no way to be neutral on that issue.
These are two issues of terminology that we care about, but they are not similar issues.
Calling the GNU/Linux system "Linux" is misleading and unfair to us. We don't publicly work with people who do this.
Speaking of "open source" is not misleading or unfair. It simply means endorsing a view that disagrees deeply with ours. It isn't dishonest. We can work with people that hold these views, when we and they have common interests, provided the joint activity acknowledges the free software movement. (It could be called a FLOSS activity, since that acknowledges the free software movement.)
