That argument can well be made, given how (un) effective it is. But what would be the alternative?
You are not alone with your view, in a sense Meta, Google and AWS as well as most social media platform act like they don’t think they need to have such controls. They just provide the platform.
By that logic AML/CTF controls would need to stop for banks and all others. Processing a payment for murder would become OK. Even though the killing would be a criminal act the payment processor would not have any obligation to support the investigation, they just processed a payment.
Is that aligned with your moral view?
