"We are constantly improving our security and this underscores the fact that there are constant attacks," said CEO Mark Zuckerberg. "We need to keep focusing on this over time."
He said it, but I do not think it means what you think it means. "Constantly improving" would seem to indicate that things are actually going to get better when in reality it means that while they do patch the occasional vulnerability, there are more discovered than will ever be addressed. Saying there is a need to do something doesn't mean that something will get done and it certainly doesn't mean that what gets done will have a meaningful effect.
