Facebook attack was not targeting just them, but all iOS developrrs

The article at http://arstechnica.com/security/2013/02/facebook-computers-compromised-by-zero-day-java-exploit/ had an interesting section, which implies that it was targeting FB but all possible iOS developers:

Facebook's internal security team worked with a third party to "sinkhole" the attackers' command server, taking over the network traffic coming into it from systems infected by its malware. They discovered traffic coming from several other companies, according to Facebook Chief Security Officer Joe Sullivan.
