Well someone did.
Here is a direct quote from the video of the priest in his homily:
In his homily, Father Faber made a point of saying that Cardinal Schönborn expressly approved this celebration. Despite the fact that Gloria TV had documented liturgical abuses during the previous years, Despite international exposure and world criticism, Cardinal Schönborn stands behind the event.
The following is the complete translation of the gloria.tv video of Cardinal Schonborn’s expressly approved Unholy Mass:
On the 29th of June, the pastor of Vienna’s Cathedral, Father Toni Faber celebrated the so called Western Mass at the Danube Island Festival, for the third time. The Danube Island Festival is an annual large open air music festival in Vienna.
