The European Commission announced Monday it will probe Facebook's purchase of customer relationship management platform Kustomer.
The commission cited concerns that the deal could enable Facebook to stop Kustomer's rivals from using WhatsApp, Instagram and Messenger to communicate with customers. The commission said it was also worried that the deal could increase "the data advantage of Facebook."
"Our investigation aims to ensure that the transaction will not harm businesses or consumers, and that any data that Facebook gets access to does not distort competition," said Margrethe Vestager, the commission's executive vice president.
The U.K.'s competition watchdog opened a probe into the acquisition on Friday.
