And I would argue that to the general population (non-HN/tech types) a VPN is the "Pirates Bay" of banned or ID law content. Porn ID law goes into effect, tens of thousands of people suddenly sign up for a VPN. If they thought of it as "shielding your traffic while using a public network" they wouldn't be signing up en masse when laws happen that they want to circumvent; they would have already been using it.
As for ICEBlock et al, knowing they are raiding in a part of a city that happens to be on someones running or cycling/walking route while being a darkly pigmented citizen is a valid use of the app to know to stay clear of the area. It should not be a thing, but it is.
