Where is the PRO argument?

I don’t see any arguments on the PRO side. There are declarations about Heidegger’s much discussed anti-semitism, yet there is no obvious relation to the Freiburg decision, because it was taken before the Schwarze-Hefte. The Arendt-chair-idea is nice, but not PRO. The only argument I find: 3 chairs for X are needed to remain relevant in the field. No philosophy institute in Germany has 3 chairs in any X, thus no relevant research in any X. This is very dubious. On the CONTRA side: mostly correction of misinformation. I don’t see why a philosopher should sign this petition.
