The 5 main issues with Messenger

Lack of Transparency - Opacity in operations, data handling, or supply chains, making it difficult for users to understand practices.

Meta lacks transparency in its data collection, sharing, and security practices. The platform has been criticised for not disclosing how user data is used, shared, or protected, and for failing to provide clear, accessible information about its privacy policies and security vulnerabilities. Regulatory actions and whistleblower reports have further exposed Meta’s opaque operations.Source: The Register: WhatsApp’s lack of transparency in security reports, The Verge: WhatsApp banned by US House for lack of transparency

Data Monopolies - Control of vast amounts of user data, creating risks for privacy and potential misuse.

Messenger/Facebook shares extensive user data, including phone numbers, device information, and metadata, with the Meta ecosystem. This data is used for targeted advertising and to enhance Meta’s data monopoly.Source: WIRED: WhatsApp has shared your data with Facebook for years, The Verge: WhatsApp links accounts to Meta’s ecosystem

Privacy Concerns - User data is likely to be stored and used against users' best interest.

It took Meta seven years to enable Encryption for Messenger by default. Anyway, metadata will still be shared across Meta's ecosystem.Source: WIRED: Why It Took Meta 7 Years to Turn on End-to-End Encryption for All Chats (2023)

Big Tech - Big Tech companies do not nourish people and planet. This is especially true in times of political tension.

Meta is one of the biggest tech companies, gathering massive amounts of data, also through its messaging app Messenger, utilising it to feed users personalised ads and manipulate them with misinformation.Source: The Verge: FTC v. Meta antitrust trial over WhatsApp

Misinformation / Manipulation - Spread of false or misleading information, often through algorithmic amplification, which can harm public discourse and trust.

Meta retired fact checks for user generated content on their social media platforms. The company also profits from scam ads that harm its users. Sources: Techspot: Meta knowingly took in billions from scam ads, ArsTechnica: Meta axes third-party fact-checkers in time for second Trump term
