Back in March we published a blog post outlining our commitment to Tableau Public - you should read this to understanding why it is important to us.
We also published a Tableau Public data policy which is similar to the Digital Millennium Copyright Act. If you're interested in how we'll react to controversial data being published, you should go read that post. Robert Kosara (@eagereyes) posted a reaction to our policy.
As always, we are interested in your opinions and welcome feedback on these policies.
