This campaign is mainly focussed on drugs related crime syndicates, having a graphene phone is seen as criminating evidence. Dutch police has a very competent cybercrime unit, a few years back they cracked a secure “pgp phone” network which exposed multiple drug syndicates and led to a large amount of convictions.

That said, stopping crime is always used as an excuses for states to crack down on privacy and other human rights. Its a slippery slope.
