Very confused, is this all BS?

“Confer, the private AI chatbot launched by Signal creator Moxie Marlinspike, uses that Nvidia-based TEE setup— along with an authentication system…”

“Meta, too, uses a TEE to offer a more private version of the Meta AI chatbot included in WhatsApp—a privacy system that Confer’s Marlinspike has said he is helping Meta to develop.”

This feels too good to be true and I am surprised this article is the first i am hearing about the relationship between Marlinspike and Meta for this product.
