I don't mind Reddit fucking up. If they were competent they would have monetized the users a long time ago and it would be an broken mess that feeds daily spam to my inbox like every other social media platform. Reddit is too valuable to take seriously.
It's like an ISP knowing a significant portion of your web browsing behaviour.
If you're concerned about the outbound link issue, disable javascript. A cursory look at the page source should convince you that that's the only way they can track outbound clicks.
And since now we know that the CEO (at least?) has edited comments, users' comment history should be considered suspect..
I know someone in high school who joked about murdering someone and he's doing 25 to life for it now so I've learned to realize that someone joking about something is in no way proof that they wouldn't do it.
Also, in what way would he NOT be looking at dark secrets of people? Reddit makes money on selling packages of personally-identifiable information / and IPs so that you can pay them and be able to link reddit accounts to facebook accounts and google accounts and so on. People think they have some sort of anonymity on Reddit but if you pony up cash Reddit will strip anyone's away for you. And I'm sure he's looking at what he's willing to sell to others. If anyone posts something juicy but anonymous on Reddit, he's looking at their real name attached to their facebook account.
