Am I wrong to be upset that I learned of my uncle's death via Facebook?

My uncle recently died. We weren't close, but I would have expected a phone call from my parents about it. Instead, I learned about his death via a Facebook status update from one of my cousins (not his child, but his niece). I've been really angry that I learned such momentous news that way, but I'm having trouble explaining why to my family. Am I wrong to be upset? If I should be upset, what's wrong with what happened?
