The point is Flock intends to expand their product offerings far beyond license plate reading. It has to do with Flock's AI because all the features in all the products will converge on selling surveillence of civilians. All their products will feed data to all their other products because centralized data makes their features more attractive to LEOs. The further embeded they are in an investigation the more they maximize profits for shareholders. The math is pretty simple.

Also the thing not being mentioned anywhere in this thread that is in other reporting is that the Flock partnership is an interface for police to ask the Ring owner to share their footage with police. A thing that police can already do under the current system. It seems to just be a "single pane of glass" for both systems.
