Someone wanting to store data on chain is not going to be dissuaded by changes to op return especially if they are trying to store csam or other data that is broadly seen as illegal. This type of data is an attempt to attack bitcoin and it makes no legal difference if it is in 1 large op return or several or it forgoes op return and uses a key stuffing technique.

Your attempt to make this a moral issue is the telling aspect. Bitcoin is neutral technology and has no opinion on the morality or legality of how it is utilized.
