Re: [Osdc-list] Secret out: Twitter has a separate feed for promoted tweets

It sounds to me like this is some good ol'-fashioned reverse engineering aimed at discovering precisely how data are collecting, distributed, and controlled. But that's not to say there isn't an open-sourcey angle here! If Twitter were more transparent about their deployment of so called "Promoted Tweets," all this reverse engineering would be necessary (one could simply look at the code).

For clarity on what was slightly confusing to us...the article says:

"Fortunately for us, the app was written almost entirely in Objective C, which meant that we'd be able to examine some of the app's source code as it was written by Twitter's very own engineers; usually, when disassembling C/C++ binaries, source code loses its original naming symbology, but Objective-C preserves a lot of symbols which makes it easier to follow along."

Then goes on to show how they investigated the code:

"Using a nifty tool called class-dump, we began examining the contents of Twitter.app and how it was designed."

I think the question is...because of the way the code was presenting, did this allow the folks "hacking" on this to do this sort of discovery and is there an open source angle to that?
