You can't "generate" CSAM. CSAM definitionally had to be about abuse of real children. It's still bad and should be illegal but lumping them together is bad.

If I use a shovel to kill a man, the shovel maker did not engage in intentionally crafting a weapon of war.

How tools are used are a reflection of the people who use them, and I definitely sympathise that tools should have guardrails to not enable this, or at least detect it.

But if a pedophile uses Whatsapp to groom a child; I don't go after Whatsapp for being a neutral service... I go after the pedophile.

You're the one wanting to generate that though
