I'm suggesting that at the very least, the money in Twitter wants not to lose their money. Twitter has been under the microscope of late as their numbers start to wear thin, as their revenue streams start to pan out and as they start to get more press for harassment than breaking news. As a consequence, Twitter issued a "there there, everything's okay, we're more than just a rage engine" and changed policy and code. Not saying it'll mean much in the end, but it got the subject changed from Twitter to "something other than Twitter." Reddit has pretty much been one long downhill slide of bad publicity since Obama showed up to do an AMA. This is the sort of move one makes if one wishes to staunch the bleeding without actually doing anything.
