Business Hosting & Content Access: This is paramount: When a business chooses to use Meta's secure hosting services to manage their WhatsApp communications (a feature aimed at larger businesses), then the content of those messages is decrypted on Meta's servers (acting as a service provider to the business). At this point, the business, and Meta acting on its behalf, can access and potentially use the content of these messages. Businesses may use this information for their own customer service, marketing, or to personalize advertising on other platforms. This is the primary mechanism through which Meta can directly interact with message content, albeit in specific business contexts and not for personal E2EE chats.
