The American Federation of Teachers has pulled the plug on X, marking one of the most significant departures from the social media platform since Elon Musk’s controversial takeover.
The union, representing 1.8 million education workers across the United States, cited disturbing AI-generated images of children as the breaking point in their relationship with the platform formerly known as Twitter.
AFT President Randi Weingarten didn’t mince words when announcing the decision in a Reuters interview on January 13, calling the images “sickening” and declaring them the “last straw.” The union ceased all activity on both Weingarten’s personal account, which had amassed roughly 100,000 followers over 15 years, and the official AFT account, with its 75,000 followers as of January 14, 2026.
“If you’re on Team Humanity and you believe we have to protect children… you have to draw this line,” Weingarten told Reuters, emphasizing that protecting young people outweighed maintaining their social media reach.
The Grok Controversy, X Under Fire Over AI-Generated Explicit Imagery
At the center of this drama is Grok, an AI-powered chatbot created by a company called xAI, founded by Elon Musk, and is a part of X itself. Unlike other mainstream AI models, Grok is capable of creating “hyper-realistic images” that include very disturbing content such as those involving sexualized imagery of kids in bikinis, undergarments, or nude.
Such pictures have ended up all over the platform, raising grave concerns about content policies and a lack of safety for young users.
Although X recently changed some of Grok’s configurations so that people couldn’t share such pictures on the platform, Grok can create these pictures in private, a measure that fails to address the issue at all.
When the matter was raised with xAI, the response that came from the company was generic, and there was no reaction from X itself on the particular points that were raised by the teachers’ union.
A Growing International Crisis
The problem extends far beyond X’s platform boundaries. The UK’s Internet Watch Foundation confirmed finding Grok-generated images classified as Category C child sexual abuse material on dark web forums as early as January 6, 2026. These images depicted girls aged 11-13 in sexualized or topless poses material that would be illegal to create, possess, or distribute in most jurisdictions.
The discovery has triggered alarm bells internationally. Indonesia is reportedly considering banning Grok altogether, while child safety advocates worldwide are calling for urgent action to prevent AI tools from being weaponized for exploitation.
Why the AFT Finally Cut Ties After Musk’s Acquisition
As for the AFT, it seems that the use of AI-generated images by the platform is the result of a continuum of irritations the organization has experienced rather than a singular example. As explained by Weingarten, such issues have been rife on the platform since Musk’s acquisition of the platform for a staggering $44 billion in 2022.
The union had been loyal to the platform in light of these previous controversies because it provided an essential means of communication with members and the general public. The use of children with a pornographic message, however, marked a point of no return.
“We prioritize children’s safety over our reach,” Weingarten stated, articulating a position that puts the organization at odds with the platform’s current direction.
Protecting Children Over Platform Reach: The AFT Exits X
The AFT’s departure carries symbolic weight as one of the first major American organizations to explicitly leave X over child safety concerns related to AI technology.
As a union representing teachers and education workers, professionals legally and ethically bound to protect children, their exit sends a powerful message about acceptable boundaries for AI development and deployment.
The incident also highlights broader questions facing the tech industry: Should AI tools have the capability to generate any image users request? What responsibility do companies have when their products can be misused for harmful purposes? And how do we balance innovation with protection for vulnerable populations?
For now, those questions remain largely unanswered as xAI continues developing Grok and X continues hosting the tool. But with mounting international pressure and organizations like the AFT willing to walk away, the status quo may not hold much longer.
The teachers’ union has made its choice clear, when it comes to protecting children, no platform reach is worth the compromise.
