I don't see how that has anything to do with the topic at hand. We're not talking about Twitter's success, we're talking about its influence on elections. If anything it's because it's been very successful (by some metrics) that it's in this position.

I'm not saying that an ultra-politicized workplace can't be an issue, I'm saying that it's silly to blame this particular problem on it. The very concept of ad-supported social networks is the issue, not the political alignment of the guy who writes the CSS.
