I would be surprised if this were the honest reason, at least more surprised than I'd be were it any other web giant, mostly because Twitter seems to have a mature grasp on why an average tenure of 2 years is insane for an engineering job and attempts to avoid the problems you mentioned. I reckon Twitter had motivations that simply don't scan well with people who enjoy using a product of yours and don't want to see it quashed.
