It's not just Twitter. Most popular APIs tend to regulate and constrain use as they grow popular. This has dissuaded developers, and certainly startups from building products on top of APIs. VCs do not like companies depending on third party APIs either, due to the fact that they may be arm twisted by the API service.

Twitter's attitude towards developers is potentially impacting the uptake of libraries like Fabric, despite having nothing to do with their API. What Twitter may have a shot at, as a result of this effort is to get usage of their libraries like Fabric on par standing ground with libraries and products like Parse from Facebook.
