There is some interesting material here. Certainly contemporary academic philosophy in the Anglosphere and elsewhere is over-specialized and hyper-professionalized. A critique is needed. I have given the APP effort only a cursory reading, so I won't say anything more about it now except to observe that the contributors are anonymous.
I should think that if one is serious about what one maintains and wants to be taken seriously, one should show some civil courage, speak in one's own name, and witness to the truth as one sees it. And this especially in the case of one of the contributors, Z, who describes himself as follows: "Z is a 50-something cosmopolitan anarcho-philosopher, and previously was a tenured full professor of philosophy at a public university somewhere in North America, but still managed to escape with his life." Why so coy?
Or is Z still afraid of this guy:
