Snapchat hires team to prevent rivals from stealing features

Snapchat has acquired Swiss startup Strong.Codes' team that develops tools to hide software code, making it harder for competitors to copy. Facebook has faced flak for copying some of Snapchat's features, including 'stories' tool that allows people to post short videos for 24 hours. In May, Snapchat CEO Evan Spiegel said, "People copy your products if you make great stuff."
