Explicit accusation that this was caused by chatbots + call for general regulation is right there in the article:

"AFP spoke to several members about their experiences. All warned that the world has to wake up to the threat unregulated AI chatbots pose to mental health.

Questions are also being asked about whether AI companies are doing enough to protect vulnerable people."

This, in time, might be used to nerf the models that we use. Of course, one actor is singled out:

"There has also been a recent rise in people spiralling while using Elon Musk's xAI's Grok chatbot, he said."
