I hear Flickr is back in the game.
2) Flickr has been around a lot longer than Instagram, without ever engaging in this kind of privacy abuse. Its age and past behaviour both earn it a certain amount of trust and indicate that it is unlikely to need to turn to privacy abuse for short-term monetization to satisfy investors.
3) Flickr has a plausible monetization strategy built around its heavy entrenchment in the pro community that does not involve privacy abuse.
There's absolutely no reason to believe that a move from Instagram to Flickr isn't a big, big step up in terms of privacy protection.
