EU antitrust authorities solicit feedback for WhatsApp deal

• EU regulators are now soliciting feedback from Facebook's rivals and telecoms operators, after setting an Oct. 3 deadline to decide whether to clear Facebook's (NASDAQ:FB) $19B offer for WhatsApp.
• In a questionnaire sent to third parties, the EU competition watchdog asked if the deal would have a negative, neutral or positive impact on users of mobile messaging and social networks.
• U.S. regulators already gave the deal a green light in April.
