To me it also seemed clear that there is still a lot of resentment in both Andrew McCarthy (towards Blum), and in Cryer (towards McCarthy).
I did think it was kinda funny how those two situations were kind of mirroring each other. (McCarthy pushing for an apology from Blum, and Cryer doing the same to him.)
That comment about the three guys on the cover being the "core members" was clearly meant as a jab towards McCarthy that he thinks they're both "Brat Pack adjacent".
