Paradoxically it would seem that turning a blind eye to forums that disseminate CSAM would actually help surface and prosecute physical crimes easier. There is a counter-argument that CSA happens because of some financial or other incentive for the abuser to share the material online, but that argument has always seemed fickle to me. What's happening behind closed doors will probably keep happening, whether there's a camera involved or not.
Things get a bit uncomfortable for various high profile figures, political leaders and royalty if prosecutions start happening.
The meta conspiracy theory in all of this would be that this is an actual CSAM producer trying to take down evidence that could be used against them.
It is however not at all clear the evidence they want scrubbed from the internet is CSAM-related. It's just the go-to tool for giving a site trouble for some attackers.

The root problem of CSAM is child trafficking and abuse in physical space. But for whatever reason enforcement efforts seem to be more focused on censoring and deleting the images rather than on curbing the actual act of child trafficking and rape. It's almost as if viewing (or this case, merely archiving) CSAM is considered a worse crime than the physical act of trafficking and sexually abusing children, which is apparently okay nowadays if you're rich or powerful enough.
