Monetization of the queries doesn&#x27;t appear to be a significant revenue opportunity for either Google or Facebook - why would this be different for Twitter? Not that this can&#x27;t be a revenue source, but how big is it?<p>An alternative: I agree with everyone that they should have turned the APIs  back on - they just should have made it mandatory to carry advertising as part of the feeds in order to access the feeds. They could have also layered on federated advertising for anyone consuming the API - meaning, allow those folks to show their own advertising in-stream. They simply pay Twitter a cut. Both of these may have helped them both grow the audience and advertising at the same time.
