If what is claimed about OpenFeint is true--they collected information on users without consent, sold it, and then explicitly denied collecting that information--, the CEO should have known about it. If the CEO knew about it and did nothing to stop it, he's complicit in it. Given the claim and him selling the company are within a month of each other, it's hard to argue he was unaware. To then go on and form Discord, there's no particular reason to believe that he wouldn't continue the same tactics with the new service if it's possible unless he's repudiated his past behavior and shown evidence that he's against the practice.
While I agree this is true, the point "stuff ... that you can't possibly ... know" holds for a lot of things. We don't know what all the various US government monitor has meant as far as actually monitoring you or I. We do know that they've capable of monitoring you or I and they've lied about the ability or their actual activities, even if the examples leaked were of a personal nature.
Again, read the first link. It is my opinion that one should presume that any company that can monitor and collect your information will, so the only safe protocol to use for private communication where it's impossible for a company to monitor and collect that information. Further, it is my opinion that any company that collects your information will try to monetizing that information either directly by selling it or indirectly by using that information as a platform to sell ads. In either case, almost any ToS will either explicitly tell you they will use your information, have weasel words to allow everything short of using your information today with plans to change the ToS unilaterally to use your information, or they'll just lie and use your information in breach of the ToS.
So far, the news has consistently backed up this position except in extraordinary circumstances where the people involved aren't interested in financial gain or are generally incompetent, although the latter case still leaves room for bankruptcy to sell any collected information.
