Gabriel Rockhill is a guest on Episode 208 of the Deprogram, where they discuss this issue.
Here's Sebastian Budgen (Senior Editor of Verso, Editorial Board of Historical Materialism, Contributing Editor to Jacobin) insulting Rockhill with ad-hominem attacks on social media for daring to criticize Western Marxism, and explicitly saying that he stopped the publishing of Rockhill's book with them: https://x.com/GabrielRockhill/status/2005093043012337674
This same person stonewalled the publishing of Domenico Losurdo (who wrote a previous critique on Western Marxism titled Western Marxism: How it was Born, How it Died, How it Can be Reborn): https://x.com/Huck1995/status/1682482754334732289
