If Twitter loses our data, closes our accounts or goes out of business, do we still own those tweets?

Or are they retrievable in any way?Twitters terms of service are not necessarily finalized though. Stone made it quite clear that they are still open to feedback, and will make adjustments if they deem them necessary. There is even a feedback link right on the terms page. So if you have concerns about anything within, dont hesitate to let Twitter know.
