It's a self-reinforcing problem: I imagine most startups that grow as fast as Facebook don't have a perfectly engineered architecture, simply because they're desperately optimizing their products for time-to-market. When the "Facebook has security and privacy issues, and might be evil" meme gets around, people start looking for more weaknesses and quickly find them. From my limited experience in startups, none would be immune to such scrutiny. Facebook is at a very challenging point right now: they need strong short-term PR, very fast patching up of issues as they arise, cleaning out the tech debt they acquired in their youth, and most importantly, battling off the fierce competitors of all stripes and colors: from Google to Twitter to foursquare. Will they be able to do it? Based mostly on their ability to capture as large a market as they did and their fast attention to issues as they arise, I think so: as long as they don't piss off their users enough for them to leave en masse (and they haven't - most of their users don't care about the privacy issues we go crazy over), they just need to hold on and keep doing more or less what they've been doing.
