Zuckerberg slams Apple in an earnings call, casting Facebook as a victim

“We increasingly see Apple as one of our biggest competitors,” Zuckerberg said, noting that Apple’s iMessage software is preinstalled on iPhones — enabling it to become the most widely used messaging service in the United States, as opposed to Facebook’s WhatsApp — and that Apple’s growing investment in services also enables it to compete with Facebook and other apps that use its iOS software platform.
