Outing your identity to whom? You must know that Twitter already knows about your alt accounts right? I wouldn't panic just yet, they will probably just derank unverified users in the replies of tweets so spam bots can finally die.
As the article says, the whole miscalculation comes from Twitter counting all your alts as active even when you were only using one of them...
They aren't concerned about Twitter, Inc. knowing. They don't want other people on Twitter knowing.
