Let me see what my interpretation of the rules yields. And yes I agree - we mustn't get all huffy about it - Rev, Arch, myself or anyone else involved.
Support can be cut. This will cause the order to fail and support will not be given.
Support is cut if the unit giving support is attacked from any province except the one where support is being given. The support is cut whether this attack on the supporting units succeeds or not.
In Diagram 15, the support from the Army in Silesia is cut by an attack from Bohemia. Note that it was enough to attack the Army giving support to cut that support. It was not necessary to dislodge the support unit to cut that support.

Now if we substitute Rev, Eru & Ender's moves into this example:
Substitute Eru's London Fleet for the A Prussia;
Substitute Ender's support from Belgium Fleet for the A Silesia (that's supporting);
Substitue Rev's Picardy Army for Bohemia (cutting the support).
Substitute the English Channel for Warsaw.

Hence, upon inserting the above:
In our map, the support from the Fleet in Belgium is cut by an attack from Picardy. Note that it was enough to attack the Fleet giving support to cut that support. It was not necessary to dislodge the support unit to cut that support.
