It's always funny to me when people say that sort of thing. Highly publicized attacks/vulns are bad, but it's likely that any given thing we use is getting owned all the time.
Well when we see vulnerabilities that can be traced back to boneheaded security, it seems reasonable to have some extra concern. Like when Sony decided to roll it's own crypto implementation for the PS3 and forgot to use different random numbers in one part, leading to the root private keys for the device being broken.
Surely many hacks happen that we never find out about; nonetheless, the real world consequences of both the recent Sony (Pictures) hack and the older PSN hack were quite significant. The latter was quite relevant as it meant no one could play online games on their PlayStations for… weeks? months? if my understanding and recollection are correct.
