Meta proceeded with Messenger encryption despite child safety warnings
Meta implemented end-to-end encryption on Messenger and Instagram despite internal warnings from executives that the plan would impair child safety monitoring. Court filings reveal that Meta's head of content policy called the decision irresponsible in 2019, and New Mexico's attorney general alleges the encryption made it easier for predators to reach minors, leading to real-world abuse and trafficking.
What happened
Meta executives proceeded with end-to-end encryption on Facebook Messenger and Instagram despite internal warnings from safety personnel that the plan would hinder the company's ability to detect and report child exploitation cases to law enforcement.
Monika Bickert, Meta's head of content policy, wrote in an internal chat exchange dated March 2019 that 'We are about to do a bad thing as a company. This is so irresponsible.' Internal estimates suggested that reports of child sexual exploitation could have dropped sharply if Messenger had been fully encrypted at the time.
Meta implemented the encryption plan in 2023, introducing new safety tools beforehand and later building systems to detect suspicious behaviour without breaking encryption.
Reported impact
The New Mexico Attorney General's lawsuit alleges that Meta's design choices made it easier for predators to contact minors, which in some cases allegedly led to real-world abuse and human trafficking.
Meta users survey found 19% of young teens on Instagram report seeing unwanted nude images.
Index analysis
Child safety organisations have long raised concerns that end-to-end encryption, while good for privacy, can make monitoring abuse more difficult, and platforms need stronger safeguards to protect minors if encrypted messaging is enabled by default.
Governance controls
Meta has defended its decision by noting that users can still report harmful chats to the company for review and possible referral to law enforcement, and special protections have been added for teenage accounts.
