WhatsApp for Business has significantly influenced how businesses communicate with customers, emphasizing convenience but raising privacy concerns among users. While enabling companies to send bulk messages, users express frustration over spam and privacy issues, particularly regarding group chats where phone numbers are visible. Critics argue that WhatsApp's acquisition by Facebook has degraded the platform, cluttering it with unnecessary features and making the user experience less intuitive. Other messaging apps like iMessage, Facebook Messenger, and Signal are mentioned as alternatives, often preferred for their functionality and privacy. Moreover, users highlight the global reliance on WhatsApp, including its use for international communications, yet remain skeptical about its encryption claims amidst rising concerns about data handling and privacy. The discussion reflects a broader hesitation towards using WhatsApp for business interactions due to these privacy issues and the effectiveness of spam control measures within the app.
