Mexico gives Meta, TikTok and X a month to restrict what minors see, with penalties left to a later bill

The penalty is the open question, and for now it is a conditional. Sheinbaum told a news conference: "If no progress is made, it would become a law." ^[6] The government has said it would back a bill to penalize platforms that fail to follow the decree ^[5], but the reports do not give a fine, a regulator or a definition of progress. In our view the government is holding the bill in reserve as leverage while it watches the platforms for a month.

That puts the first cost in engineering. Al Jazeera describes a decree that requires platforms to restrict exposure to violent, harassing and sexually abusive content by design, and to remove risky material from minors' profiles immediately ^[2]. If the month that government adviser Luisa Maria Alcalde described ^[3] runs from the Oct 14 signing ^[4], it ends around Nov 14 ^[14]. We think that is short for a build of that kind.

Meta's first answer points to tools it already runs. A spokesperson told Reuters the company is "aware of the decree" and will "analyze it in detail" ^[10], and described safeguards that limit who can contact children as well as monitoring of viewed content ^[11]. The decree as reported asks for restriction by design, which is a default the platform sets ^[2]. Whether the parent tools Meta cited count as that default is the point to settle. If Mexico accepts them, the cost to Meta is small; if it does not, Meta has a month to find out. Six of the seven companies officials met ^[13], everyone except Meta, had not responded to Reuters when it published ^[15].

For scale, Al Jazeera points to Meta's agreement last August to pay an $18bn settlement in a US federal case accusing it of endangering children ^[16]. That case alleged violations of the Children's Online Privacy Protection Act through data collected from children under 13 without parental consent ^[17], a different harm under a different law, so it is a poor guide to what a Mexican penalty would look like. It is the only dollar figure in the coverage.

It could go differently. Platforms may show enough movement by mid-November that the bill is never written, and the decree stays the whole regime. The government may instead judge progress short and sponsor the bill, at which point the fine schedule sets the cost. Or the questions these measures have raised about privacy and freedom of expression ^[9] may narrow what counts as harmful content. We expect the first month to cost engineering time and no fines. We would be wrong if a penalty bill with figures appears before the deadline, or if Mexico rejects existing parent tools as compliance.
