Now imagine what LogRocket could do with that data when they blended it with data from their other users, or if they augmented it with data they bought in from other services. Or perhaps LogRocket could sell the data to a broker, and then on to [Meta|Google|me].

That's what you're doing to your users.

I'd consider that something to see.

(I don't have any evidence to believe LogRocket are doing this; LogRocket is just the example. Other tracking services exist, and they sure as hell do do this sort of thing.)
