The comments are interesting,too.

Thanks for this explanation. Surely, as you state, this must have been a difficult decision in some ways. You owe it to the growing base of citizen journalists, open data advocates, and Tableau enthusiasts/practitioners to fairly and evenly apply the terms of service by which we all agree when availing ourselves of your generous offer to host our work. The perceived “value” of the the data being shared is something that you do not judge per se, and it is clear that you have not sat in judgment to date. And, the “value” of any data hosted on Tableau Public fails as a criterion of entitlement.

On the other hand, as in this case, it looks like right-to-use flunked the test. So be it. This should not deter anyone from using Tableau Public as a technological tool to advance the public good. In fact, your commitment to contributing to a better world should hearten all your many fans and comfort even the harshest critics of this decision.
