Not related to encryption, but "child safety" seems to be a really popular subject for ushering in all kinds of overreaching policies.

Encrypted communications? Think of the children.

Legalizing cannabis? Think of the children.

LGBTQ+ rights? Think of the children.

Non-western immigrants? Think of the children.

Non-western social media becoming too popular? Think of the children.

etc.

Sorry if this was political, but every time I see someone use "Think of the children" as their main argument, I can't help but to think there's some ulterior motives, and kids (who can't voice their opinion, or won't be heard / taken seriously if they could) are just being used as pawns - because who would want to argue against the safety of kids?
