To "call out" someone means to call or draw attention to that person's inappropriate or unacceptable behavior. Basically, it means to address someone because their actions are wrong in some way. In this context, "Google quickly called out the responsible agencies over social media" means that Google used social media to address the actions of the responsible agencies. Ex: Stacy called out Joe for cheating during the test. Ex: If you don't call others out when they do something wrong, they may continue to do it.
