There is no allegation that anyone was trying to spy into the house. (But who wouldn't want a look inside?)
The photographer was behind some bushes on the road. Now, if someone popped out of a bush at me I would be startled....freaked....frightened. Meghan is smiling right into the camera.
Of course, one way to make sure that does not happen is to hire a discreet security crew. I would think Harry would want his family protected from.......oh I don't know..........kidnappers? It is a public road.
oh there is another article about that issue.
