There are plenty of times that I want to share something with another person. This could be a link, a slice of data, or maybe the view of some page I've seen. Many applications make this easy, either on the Internet, or inside a company in Slack or Teams.

However, there are lots of times that I might want to share some data publicly, allowing anyone to get to it. That's a place where no shortage of data breaches have taken place, a problem we still grapple with today. It's not a "make-a-decision-once" problem either. I could set up some data for access to specific people using permissions. Then someone later changes to anonymous public access, mistaking some dataset that is sensitive for one that can be exposed. Likewise, I could have a dataset that I have set to be publicly available change, with sensitive data added later. The individuals adding the data might not be aware that this particular set is being shared without any controls.
