If you wouldn't want to share it with the clerk at the grocery store, don't put it on the internet. Period.
There are lots of uses for the internet where privacy is expected. Perhaps a better thing to say is "If you don't want it shared, don't put it on a social networking website".
It's true that once digitized, content can be very difficult to contain, but there _are_ ways to communicate over the internet and maintain a reasonable expectation of privacy.
The thing with Facebook is that they've promised certain things, like that you'd have to authorize anyone before they had access to any of your data, or that certain things would remain friends-only, or whatever, and then they've renegged on these promises. They betrayed and jeopardized their users for their own immediate profit. Do you think that's something we should just write off as "well, don't put things on the internet"?
It's not like a bunch of nude photos that someone uploaded to a server in a public directory and hoped no one would ever stumble across them. For that, you can say "well, be careful what you put on the internet, because it's just as accessible to everyone else as it is to you", but when a company makes a covenant not to share certain data and then breaks it, I don't think it's really fair to expect users to expect that behavior.
If you don't want it shared, don't put on the internet.
(Well, at least, not until my startup is shipping its product. Then you'll be fine.)
That's literally like telling me I shouldn't trust my employers with my direct deposit info and my social security. Or that I shouldn't trust the insurance company with the same information, etc.
How is a privacy policy, changed behind users backs, with blatantly offensive auto-opt-in/out features not a violation of a reasonable expectation?
>There are tons of stupid users
What is your opinion on consistency?
More important though, are diligent users like me, who still managed to have private data shared with third parties against my will with absolutely no notification that it would be occurring.
There are tons of stupid users that don't bother to check their privacy settings but I swear to God, I've edited and locked down mine 4-5 times in the last six months and I have to be vigilant about it because THEY SILENTLY CHANGE THE PRIVACY POLICY & TOS AND RESET MY PRIVACY SETTINGS.
Let's all go against the flow and defend Facebook. Right.
