Saying "we don't care who the 10 people are" is a world of difference from "there are
no restrictions on the 10 people you can share with." It is not implementation details that are defined in a contract. It is not information.

Yeah I guess it's moot now, but at this point I always interpret a lack of specifics when talking about a product as marketing speak. We have fact sheets, we have plenty of discreet, unambiguous information of other features; when somebody goes out of the way to hype up a feature of a product while painstakingly avoiding concrete, verifiable information about said feature, and verifiable information about said feature doesn't appear in the previously mentioned fact sheets, I assume the feature doesn't actually exist yet. Especially when an executive goes on to literally say the feature doesn't exist.
